i have yet to see anyone get anything more out of the SP-E intake than what CP-E did. so why is the tunable option worth anything? nothing against CP-E, but dyno operators laugh when i ask if they tune the Haltech which is a full standalone....after seeing how the CP-E software works, i think they'd spit on me? it's good, but they know it, and set it up right, from the getgo.
true, you need to send your ecu to Jet, but it's a 2 day turnaround, AND they "claim" to remove/raise the limiter for those interested in that
again, these are just my thoughts. i had the cp-e intake on my 6i atx, and i've played with the tuning on Atomwat's V6. it's fun to play with, but that doesn't mean you can make your car faster with it
....edit....as far as the cost goes. you can buy cpe for $530, and sell your AEM for say $100, so even with that in account, Jet is still $30 cheaper or so. i would just confirm things with JET first....again, just me
