So I was doing some research on intake manifold mods and came across something the guys at GS put up. Has anyone done this mod? Any noticeable gains?

Yeah I have one in the garage I want to put on but the A/F ratio thing scares me. I asked nick about it and he said it is bad without a custom tune. He wouldn't say if it runs lean or not though. Jak thinks it may be alright but a dyno session is strongly advised. So I really don't know how safe it is, I would guess that on a mild setup like mine the trionic could compensate but I am not fully sure. Since brewtide is a slacker and never went to the dyno one of us needs to just go so we can get this cleared up. P.S. just kidding brewtide don't hate me you have been very helpful.

Are you running an MBC? I am so this means if things go wonky the ECU can't pull boost which of coarse is very bad. You could remain safe by raising fuel pressure but that is not ideal because you would be increasing fuel through the whole RPM band and not when it is nessisary. The thing that sucks is that if you don't live near a tuner then it makes it hard to do a custom tune. Jak says he can right a tune for it so maybe talking to him is best.

i also am suprised there is not a aftermarket intake manifold around. nick, you better get to working . would a tuned car like mine really get any benefits from it? i can see higher tuned with bigger turbo cars seeing better air flow and better numbers but what about a car with a little t25/28?
