the engine is an L96 out of a 2012 silverado, with e78 ecm. Mods are long tube headers, camaro ls3 intake manifold and injectors, larger intake and maf housing, twin plate button clutch/lightweight flywheel. It seems to start nicely but then starts to rev away on its own while its opening the throttle blade more. I added 20% to the maf frequency table, 20% to the torque model. I took away 50% from idle external load and 50% from Idle speed reserve. This is the best its so far. Wondering if im going in the right direction fuel trims are still adding roughly 18 percent so i was gonna add more to the maf frequency table. Thanks in advance.
