I love the guys at Fastrax. They have a ton of good products, but sorry if I want something ported it goes to Turbotater. That's his name on the forum. FTX has good porting, I just prefer Wayde's principles in porting.
My turbo he picked up bottom end and gained me. 2-4 lbs of boost on the big end.
Quick turn around, reasonable price, super nice guy, it's tough to beat. Heck if he can get those purple headed monsters to run, he can make anything run.
