I barely started dialing in my tune with V3, and noticed MAFraw (running 2g stock maf on 1g car) values look very erratic during part throttle even with constant rpm. Both valve cover lines are vented and the PVC hose from TB is blocked off. Looking at other posted logs from other memebers, maf values usually looked smoother than what I have going on. Boost leak test was done and everything is healthy. Certain spots jump 175-200 hz in .2 of a second. Before I spent more time tuning, I just wanted to check with the experts if this looks typical. If it matters, Manley/Eagle built 2.0, Kelford 272 cams, EVO 3 intake mani, 2g head, 880 FIC injectors, 37psi base pressure, recirc Forge BOV, 4" FP intake tube (no breather tubes for unmetered air), and pump gas. Thanks, Steve
