RE: injector question
Thats correct. The orange is 19# and the 21's are pink. 99-01 came with 19's and the 02-04's come with 21lb. If you switch to the 21# injectors you will need a MAF particularly tuned for 21's. There isnt much of a difference, but I just went through this with my buddys Saleen.
You can get the MAF for a '02 GT but you will need a new MAF wiring harness because they changed out the Temp charge sensor position and its now incorporated in the MAF. All it is is two new pins in the plug and each one is on either end of the plug.
