I decided I am going to decat my 2010 F4 and I've seen a lot of info on tuning for aftermarket exhausts, but not as much for decatted stock exhausts. I would imagine a decatted stock header requires a similar change in tuning as a catless aftermarket exhaust.
So what's the difference between a Race ECU, Eprom chip, Power Commander, and Microtec? Am I leaving any options out?
Does a decatted stock exhaust need a tune at all?
Thanks
