injector pulse width I checked my injector pulse width because I want to upgrade my cylinder heads and was wondering how close they were to being maxed out.
My stock injectors are at 16.65 ms at 6000 rpm. I calculated that to be 83%. Is that right? I was suprized because I have a small cam and headers and stock heads. Will I need bigger injetors for ported heads?

({GM.IBPW1}+{GM.IBPW2})/2*{SAE.RPM}/1200
how good is your tune?
i had stock injectors with 383ci and was @ about the same IDC
with a "professional" tune.
when i started making my own adjustments it rose up to 100% IDC.
most people upgrade the injectors with your mods.

well i am running my afr at 12.8 to 1 and my timing at 23 degrees total. its at the edge of pinging, the computer isn't backing off the timing but I can here the motor slightly pinging at full throttle on hotdays. (it has a quite exhaust). What injectors do you recommend for 450 rwhp?
