Anyone done the horsepower freaks mod? I am planning to do this mod. Can someone tell me if it safe to do this mod and is there a substantial performance gain with this mod?
Do you have to put your turbo's back into sequential. I removed the egcv, I can't go back to sequential if I wanted to. Is it okay if I keep TTC? If not why? If I can, what are the drawbacks?fitchbuck said:
You'll pick up about 30-40 rwhp. You'll want to put your turbos back in sequential. After you do that you will wonder why the heck you had them in parallel anyway.
