FAST 90/90 need a tune?
FAST 90/90 need a tune? If I do the FAST 90/90 will the car need a tune to have correct fuel tables or will it be fine? What gains should I expect with my mods in my sig?

Oh yes! You will definently need a tune to bring out its full potential, but I don't see a cam in your sig if you still has the stock cam I would suggest that you put in a big cam now with the FAST 90/90 and get a tune all together. You might also want to do a search and find out what other supporting mods is good to go with the FAST setup. The FAST 90/90 might be too much for your setup if that is all you have in the sig.
The second thing listed in my mods is a Cam...its 218/225 @.050 112lsa. I know a tune to unlock full potential, but just makin sure I wont be runnin lean or somethin and ruin the motor. It has a tune on it right now, but that was before the cam. Also, Ive hear the "tony momo" porting is good, who is he? Whats his screen name, or where do you contact him at to get it done? If this is an over kill for my mods, does that mean ill lose low end tq or something?
What size is the stock TB?

you will be running lean, you get all kinds of extra air that the computer isn't aware of. the big intakes does provide you with a lot of extra air (i've seen 10+lb/min of difference, which is a lot) and it would be stupid and dangerous to not account for it.
