I had the stock IHI on it prior, so there is definitely a difference. The IHI would be all in about 500rpm faster than this setup. This definitely has more pull though, but I had to turn up the fuel pressure some to make up for the increased air. My wide band at full throttle is at 12, I would like to be a little richer, but till I get the Pimpx in it ,this is what I have to work with. I will say, the IHI was really fun on the street with near instant boost, so it depends on what you want from your car. Many on here run a straight T3 and I think it would be a perfect street turbo. My .02.

I didn't notice a difference except the kick was more that stock by far
