You'll probably peg it with a Twin Turbo set up. The 90mm Lightning meter only flows enough air for about 480-500rwhp and the 80mm Lightning meter is good for less than that. I'd start looking at one of SCT's units if you want a 90mm meter good for more than that.Redsnake2 said:I have the same MAF with 42lbs injectors, but I'm going with a TT set-up so i should be cool..
