Added Mild Cam and Injectors Max'd Out? I've got a 2001 Z28 and added a mild 212/218 .522/.529 cam. HPTuners shows my injectors at 20 ms @ 6,000 rpm, which is 100% duty cycle.
What capacity are my stock injectors? Any recommendations on bigger injectors if I need them?
Thanks for the help!

My cam is similar to yours and my stock injectors peaked above 95% duty-cycle. I replaced them with Ford 30# injectors and the duty-cycle now peaks at 77%

I have a 2000 SS so 26# injectors. I locked the converter and locked it in 4th gear and logged some wot stomps. I was suprised to see my injectors @ 87% duty cycle off of that. I have minor bolt ons, headers, ory, lid, ported tb, and a few others. I decided that it was best to go ahead and buy new injectors. I bought a set of 36# FAST injectors and logged a hard core wot stomp and saw 60% duty cycle.

What would be a typical duty cycle for a bolt on LS1 with 26# injectors????
