Ok, so here's the problem. car sat for about 6 months while i was working, got home and started just fine. drove it once, bov vacuum line was melted so i fixed that and it was good again. drove it the next day without issues.
the next morning it started up and was running super choppy, misfiring, and would barely drive. it sounds/feels like its misfiring but im not so sure. right now its running a garrett 2560r turbo, stock injectors, walbro 255, hks cams, stock ecu and no boost controller (10psi). i checked the coil packs and all were sparking so i know all 4 have spark. if i pull the plugs (which are brand new) they all have a little bit of fuel on the ends so i know the injectors are firing, if its idling and i unplug the maf nothing changes and the car wont rev above 3k it jumps/backfires and dies. i inspected and cleaned the maf and it wasnt very dirty. anyone have any other ideas? also checked compression and numbers were 150, 140, 135, 140. cylinder 3 is a little low but not low enough to cause this....
