This may be a dumb question, but I was considering putting in an exoticspeed exhaust, and I already have in a stillen intake. I'm considerinf maybe some other smaller additions, but a buddy of mine asked if I would need to get an aftermarket ecu to adjust my settings so my car can run at it's peak performance with the mods. Do I need one? Or will my stock ecu have some room to adjust to the exhaust and what not? And if I do need one, where can I get one? Thanks in advance!

Thanks, I appreciate it!

 

I ran just an R2C intake and Exoticspeed exhaust for a little while before I got a UpRev tune. On the baseline, the AFR was all over the place. Added a plenum spacer and after the tune the AFR was smoothed out and got big torque and power gains, especially low end torque. Definitely makes the car run so much better and takes full advantage of your parts.
