Heads and cam car. This year I changed the heads, went to LS3 injectors, FAST 102 intake, 102 TB, etc.
At first I thought it was the MAF but apparently it's not. No matter how much fuel I add to the VE tables it still goes lean above 4000 rpm even with the MAF unplugged.
Fuel psi is perfect and never drops. I have new pump and I changed the fuel filter at the beginning of the season anyways.
Injectors were flow tested and showed 42#s which is what they should be for LS3 injectors.
What am I missing here?
At 4800 RPM and 40KPa, my cylinder air mass is 0.30 g/cyl on the log, but the VE table is commanding on the order of 0.8. Attaching log and tune file with MAF unplugged.
