What is available to boost performance and economy for the 2nd generation M6? With so much electronics, does any of those chip program help. This is my first modern vehicle and am anxious to see whats out there.

You may want to look into the isports mod thread.
The basic engine mods are the best to start with (intake, headers, exhaust, etc.)
As far as any chips, I don't know of any for this car.

I wrote a huge reply with everything listed and while I was checking the legitimately of my sources I accidentally I had basically lost 20 mins of writing so I am crazy pissed while I am writing this. I too have the K & N CAI for something like 5.5 HP.I also own a custom exhaust system gives you much throatier sound opens up few horses maybe and little better throttle response. The second cat delete lets the car pull a little more but it's basically a requirement if you are looking to get the msds header, which I advise you do (I love mine). The awr racing engine mounts let you put more of that power down to the ground quicker and they make all three of them. The EGR re-route is something we all should seriously consider:DIY: EGR Re-Route (Re-routed properly pics page 5). You could also ground your throttle body for an added touch of power or go with something more proper like a voltage stabilizer:Voltage Stabilizers Can Increase Power And Torque - Fact Or Fiction - Import Tuner Magazine. I am seriously considering buying a sun hyper voltage system very soon. Upgrading your stock resonator with an high flow one also adds a little bit more pull. You definitely want to know of the advance timing mod:http://forum.mazda6club.com/engine-drivetrain/256072-advance-timing-mod-not.html. I have also looked at the dynotronics remap but you have to send them your ecu if you don't live close and I am a little worried that they don't have the car or vehicle specific info to work with such as altitude info or what all the new exhaust mods might have done. I would say throttle body coolant bypass but after seeing this I am not so sure:http://forum.mazda6club.com/engine-drivetrain/132355-why-not-do-throttle-body-coolant-bypass.html. Of course there is the head package by gude performance that puts all these mods to shame with a 45 HP increase for the 4 banger claim, on the phone. It's $1650 for the head package if you send him your parts or he can buy new parts for $350 and you can send him your stock parts back later and get the $350 back. I would love to get my hands on this baby! I think if there is some intrest we can get an underdrive pulley made by unorthadox racing for $250. And I am almost sure somebody made a crankshaft for it but I can't find it now. There you go bud all that I gathered about dyno curve mods so far.

Thanks Holgram, I appreciate the legwork, I'm in the process of finding some time on a Dyno to help my find a vibration that Mazda refuses to recognize, but when I can make sure that the engine is good enough to mod and I get outside of the warranty, I'll get right on it. I see some of the stuff I can do now but the big stuff will have to wait.

I will definitely call the people at Supersixmotorsports about the lower intake porting. As far as the EGR reroute I came across this:New egr delete kit - Mazdaspeed Forums. It means you can just unplug the EGR and the valve will be forced shut and no leak will happen as long as carbon build up isn't disabling the valve from closing completely. This means it costs less, is easier, you don't have to worry about vacuum leaks and it's also reversible. At first I saw, basically, Magnets that attach to your fuel line:SUN AUTOMOBILE�@�yInazuma HG�z. They claim magnetized fuel will be more atomized thus more efficiency due to more surface are for combustion. Soon this research led to the fitch fuel catalyst which acts like a permanent fuel treatment in increasing the octane of the gas but I cannot understand exactly why running the gas over some sort of platinum alloy results in a benefit. When I did call them at fitch fuel to ask them if is cost effective in terms of performance gains, the woman on the phone was sure that I would see a performance gain:http://www.summitracing.com/parts/avp-f3624/overview/year/2011/make/mazda/model/6. She said the model approved for 1st gen mazda 6's will also fit 2nd gens and was talking about a 3.5hp to 12hp (I told her 12 was ridiculous and I expected 3-4) gain along with smoother idle. I do not know if this catalyst also magnetizes the fuel. My Mechanic told me we should just take the first cat off as well since it doesn't do much without the 2nd cat doing the main emission reduction. This would provide slight more sound from exhaust and a little more performance due to less restriction in the exhaust system (more free flowing). Massive Speed balance Shaft delete kit frees up a whole bunch of rotational mass:Massive Speed Balance Shaft Delete Kit - Massive Hardcore Racing Performance Parts - Massive Speed System - Ford Focus Specialists. It is very cheap for the amount of drive terrain loss it reduces but it will introduce destructive(not incredibly significant but so much so that they felt the need to include the part in the first place) vibrations to your engine and the cabin. Some people swear by this mod but I wouldn't put it on a daily driver, at least not now(or until I have heard more good things about it). Massive speed also makes a underdrive light water-pump pulley: Massive Underdrive Light Pulley Systems - Massive Hardcore Racing Performance Parts - Massive Speed System - Ford Focus Specialists. This Would also free up some rotational mass along by underdriving the water-pump pulley. This leads to elevates the engine temps but only slight. Because the only pulley with a dampener in it is the crank pulley this pulley doesn't add destructive vibrations. It requires a longer belt since it is larger than the original pulley but looks like a good mod to do. Of course an electrical water-pump would free up even more horses by eliminating the need for a water-pump pulley but I haven't found one for our cars. I have also called Dynotronics and we do not need to send them our ecu's any longer. You can either buy the interface cable for 180$ with free shipping or rent it and the tune is 450$ and they tune it wirelessy trough your laptop (cool huh?): Dynotronics Tuning - ECU Tuning | Flashing | Remapping | Chip Tuning | From Mazda to Kawasaki and More. This way they get the altitude and temp info for the car from its ecu thus its tuned locally. They also re-tune for free if you do any performance increasing mods. This looks really good for me. My first post also gave the impression that it was either a voltage stabilizer or a throttle body ground mod but this isn't the case. Both will result in a smoother more consistent charge but work separately, but I doubt anyone can seriously feel the difference with a grounding kit after they already did a voltage stabilizer (opinion, no experience).

I've contacted dynotronics and they say that they have tuning available. I read over on a 3 forum that they are going to test 2 of there cars to see how it works. I'd be willing to try it out on my 6 if anybody else would try and see if maybe we could get a discount.

Dude I am definitely in! But I was waiting for a super-charger or some head-work and milling for higher compression (as I use 110 octane) to do it. I called them for 2.5l, with all the mods on the signature, for some advance timing on spark plugs for, pure gas 130 ocatane, they said over 100 won't do anything, but to keep it safe 110 will do. Still he said 20 hp (but I have an auto), so I thought maybe I contact MSD for an ignition timing system and some new NGK spark plugs first?

Or is the solution Cosworth USA (maybe they are willing to do some 2.5L work)? Their 2.3L go up to 280Hp now that's Worth playing with (especially with a big supercharger)!

Not yet but I just ordered the tune package from them(dynotronics)... I will post when the stuff arrives, which includes mazda edit and open port.
Guinea pig number 1 standing by..
Soon I will also be testing the Mustang TB on this car to see if the ECU can control it, hopefully it can. And if it does I will be ordering from BBK soon.
keeping my fingers crossed.. diving into the unknown..

Just an update...
Still waiting on the Open Port and the Software Lincense...
Hopefully we should see something real soon...

That's cool....I've had tuned and modded vehicles all my life including my current Altima and even Uplander 3.9 work van lol (engine/tranny retune/intake,etc) so once I grab a 2nd gen V6 Mazda6 this year, I'll be looking for some reliable tuning solution.

Keep us posted!

Well tried the Dynotronics tune, and well... all I can say I hope he comes up with something for the 3.7 platform. I've tried to hold out but can no longer do it, Joe is a good guy but the lack of communication just killed it for me. I just hope I can get my money back now, since I still don't have a tune.

What exactly happened?? Does it seem the vendor just isn't interested in the Mazda6 V6 platform because not enough owners are interested??

I wish I could get ahold of Dave Coleman somehow- I was a longtime subscriber to Sport Compact Car and he was the engineering editor before leaving for Mazda R&D (shortly before the magazine went under).

He's also a huge car nut/guru and could possibly lend some insight into any possible tuning options or some little known tuning vendor that might help.

I know on my Uplander 3.9 VVT v6, I run an 87 octane tune right now (and tranny performance tune) and you still gain 5-10whp due to GM's conservative tuning even with low octane.

It would be cool to gain that much with 87 on the Mazda and even more on an 89-93 octane tune...

Add in a higher flowing intake, catback (and high flow cats) and perhaps a custom ypipe, you could likely be in the 290-305hp range (crank) with a higher octane program. Now that would be sweet...

I'll add all the information from this thread to my parts and vendor thread. I'm going to get it bumped back up so more people can see that there are performance parts for these cars, they're just a bitch to find.

Also, do we know if any of the other Ford Cyclone parts fit our cars (specifically from the 3.5 liter since those seem to be WAY more common than our 3.7).

I'm also wondering if we can swap the heads from an MKZ to our car for VVT on the intake and exhaust. Anyone look in to this yet?

PS

I can say without a doubt that the Throttle Body earthing was completely worth it and not placebo effect. I measured the voltage from the throttle body to the ground bolt on my car with a multimeter and it was registering .5~ volts at idle. That's absolutely nuts to me that just because of static electricity from air running by it would cause that, but after realizing that the throttle body is bolted to plastic on one side and rubber on the other, the static really doesn't have many places to go.

I'd definitely say it's made my throttle WAY more sensitive. When I used to push down my pedal slowly to see when it would register and how high the revs would go, they'd jump about 300 rpms from idle when it finally sensed the pedal was being depressed. After earthing the throttle body properly, I barely have to touch the pedal and it will slowly climb at 50-100 RPMs in a WAY more linear fashion. No real gains in the sense of power I'd say, but throttle response is for sure much better.
