What size is the stock mass air sensor in an 03gt? I just bought a 75mm T/B and i dont know what else i need to buy to get some power. Injectors and a mass air? Are stock injectors pink?
MAF and injector upgrades are not for adding power they are for supporting power. They will add no power at all just cost money for the parts and money for a tune inorder for your car to run. Yes your stock injectors are pink.
I have a bbk CAI, slp exhaust, and a T/B spacer, Pullies and different gears. I just bought the car; it was a repo. Auto w/ 55k for 9500. What else do i need with my T/B? Injectors,MAF, and SCT?

The OEM TB and plenum are overly restrictive, at WOT, starting around 5200 rpm up wards. This restriction is largely caused by the plenum which IMHO should be replaced first if you are on a budget--here are some numbers and a narrative to back this up. At 28" H2O differential the stock '01-1/2 to '04 plenum (which is slightly different from the '99 to '01-1/2 unit) and a 75 mm TB will flow 491 cfm. This is some 30 to 50 cfm less than any aftermarket plenum* and the stock 65 mm TB. Also visible in these numbers (from Accufab's site) is that a 75 mm TB provides no appreciably lesser flow resistance at WOT. , At 75 mm and up the upper plenum/intake manifold passage becomes the weak link. The OEM injectors and MAF are suitable for just about any n/a setup. -----------------------* - The exception to this was the C&L plenum, which did not test well.
