I am in the process of going full COBB stage 3, and plan to have it panda tuned. I am currently stage 1 1/2, I have the RMM, short throw shift plate, CAI and the AP of course. My question is, do I need the FMIC if I don?t plan on track running my car. Ever. And for the exhaust, turbo back or cat back? I wanna make stage 3 power and torque, just curious if I NEED the FMIC. As it?s purpose is keep heat soak in check. And a friend of mine, whose a diesel mechanic, told me if I?m not going to track run my car, don?t bother with the FMIC or turbo back exhaust, just go cat back. Is he correct?
