Hello, im new to the forum. I was wondering I’m going to make a 3’ single exhaust and a I have a eBay downpipe after the install do I need a new map from a tuner or is there a pre loaded map on the access port that works with this? Thanks

There are no maps on the Accessport for a catless exhaust, you will need a tune. Also make sure you have upgraded HPFP internals before you think about messing with the exhaust.

Thanks! And will buy a hpfp before.
