Hey guys needing a little help. Car is a 2014 C7 Z51, LT4 Hpfp/injectors, Gsl392 kicking on at 4 psi for low side tee in just like dsx, D1SC 13psi, Alky 10+15 nozzle, msd intake, stock cam. Car made 769 on 62% E and it was a 95* day. High pressure held solid at 2900. Now its getting cooler 60-70 out and I believe making more boost and the hpfp cant keep up. I dropped all the way down to 42% E and its still dropping down to 2400ish but then high side recovers with more rpm? Which is really throwing me off? I've attached 2 pulls and my tune. Any help is appreciated. Also just fyi I have tried a GM LT4 hpfp and a brand new out of the box AC Delco Lt4 Hpfp and both do the same thing.
