This review is for the the jetperformance stage 2 module. I did notice A difference in power over the stage 1 wich is what I had in my car first. Not A whole lot maybe like 5 horsepower or so but it is noticeable. It makes your idle A little higher and A little more rough. I will be installing my stage 1 back in my car. It idles so much smoother. Also I was running the stage 1 with intake and cat back exhaust and it was fine. Just A little less power.
