Lean Stumble Problem - Tune file and datalog I have been pulling my hair out trying to figure out why I get a lean stumble whenever I snap the throttle, my air fuel goes from 14.6 to 19 for a second and then runs fine. It also doesnt really matter what rpm i'm at - off idle or at 2k still does the same thing...... any thoughts would be awsome!!! I attached the tune currently in the car, and did change the cyl volume hoping it would help but with no good results.
1999 Camaro LQ9 6.0L, 8.5:1 diamond pistons, compstar rods,manley valves, custom bullet racing cam, cometic gaskets, arp studs, 78mm precision turbo, 65lb injectors, running maf for now just got my 2bar map but not installed yet, 6 spd, NXL nitrous 125 shot, 12 psi with methenol..... did i miss anything?
