I have found info on two gm injectors:
12482704, 01-02 camaro, 28.7 lb/hr at 58 psi
12561462, 01-04 vette, 29.2 at 58
My application is a rebuilt and hopped up L29 gen 6 454 getting the 0411 ecm swap. My questions are, which has the most tuning info available, and will either one be better for my 454/0411 app?
