I just found out I was putting e36 instead of e40 in, would that make anything happen ?

The last log looks better. Throttle seems better but HPFP rail pressure is all over the place. at WOT it should not be at 1000psi. LPFP is steady and boost is good. Could be your tune, fuel blend or the HPFP is going out.
