I plan to have Derek at IMW update my custom tune with this Stage 2 intake system and FBO as soon I get my hands on it.what about on a max effort tune? that's when I would expect to see a real difference.
As reference, Derek tuned my car with the Stage 1 intake and FBO and he ended up at 376whp (up from around 305whp). I think we'll pick up a few more ponies but not sure how much more since we're basically at the limit of the MAF voltage and fuel system.
