Need your help guys. My car is at the speedshop now. The guys there want to throw on a set of Mac l/t's and a pro-chamber midpipe. They say it is a great mod and they have had a lot of success with it freeing about alot of horse's on 96-98gt's. With a good tune and chip they think they can net me about 50rwhp. I know the car needs a tune bad because it runs alittle rough after the pi intake install. My best run thus far has been a 14.4 at 96mph with 2.1 60ft with the mods in my sig. Im sure the car is capable of better if it was tuned better. My question is do you think i should go for the headers midpipe labor tune and chip which will cost about 2000 or just get the tune for now which is 699 for a diablo chip and dynojet tune for 8hrs dynotime. Please give me your advice b/c i need to make my decision by morning.
