Ecotec injector upgrade?
Saturday, July 15, 2006 8:02 PM
I have the GMPP injectors that come with the supercharger (36lb or 37lb I think?) Im looking for an easy upgrade that will work with the reflash. Would the stage one injectors from the cobalt work on an 03 rail or are spacers needed? I notice they are more the same style as the NA 02 eco ones.

What would be the point of using these larger injectors with the same tuning?

i know that is why i posted

the point is when your starting to run lean , you gotta add fuel some how , 13's for afr isnt good under boost

on my cav i went from the 30lb to 36lb droped my fuel pressure from 50 to 30 psi , and went from low 13's to mid 11's under full boost

prob not the most precise tuning , but it works , hp tuners wasnt out when i did mine , and hp wont work with the eco reflash right now
