im in the process on installing a nitrous kit on my camaro ss. mods are night fury cam, e85, long tubes, full e85 and full exhaust.
right now with the N/A tune i know timing its advance. question is how much timing should be removed for a 150-175 shot. timing at the moment is 25.5'. i know with e85 since its better than 91 octane you need less timing removed. how much timing should i start with? -4, -5? fuel pressure is 60psi. at high rpms (5k-6700rpm) it drops down to 50psi. pump duty cycle is at 90%. i also have the zl1 pump. any advice is welcome. thank you
