My question here is, do you guys think I will be maxing out my stock injectors with full exhaust lts, y-pipe) cam and heads? On a 5.3 (lm7). Some peoples post say they still have more in their injectors and some say they are maxed. If I do need to upgrade any suggestions?

Thanks.

 

My cammed 5.3, milled heads, bolt on motor with stock injectors my duty cycle was at 93-95% at 6300rpm- and that was 12.9-13.0 afr

 

Youll probably be fine

 

Im at 95-96% at 6300-6400 with the specs in my sig.

 

Yup, sitting at 96% at 6500 rpm. Youre good mate.
