I am stuck, had this engine running great in a swap vehicle, excellent drivability and quite fast at 7.90 1/8 mile with 3.08 gears.
After adding turbo and tuning MAF and VVE tables I end up with a max tq at about half engine tq at WOT and it is probaly getting worse when I increase boost. It opens throttle fully but during or after shifts it always closes to about 50%. Had the same issue without the turbo as soon as the max tq was lower than engine tq. I corrected it by changing the max torque timing table which actually increased max tq without a big increase in engine tq but now since the difference is huge that will not be enough.
I read a lot about the virtual tq tables, question is what to log and base changes on? Engine tq vs predicted, airflow vs predicted or base changes on changes I made to VVE and MAF?
Any other ways to deal with this without cheating and raising the VVE?
Specs: -72 firebird with 2016 L83 and 6L80E. Running FPCM, Ethanol sensor but currently on gasoline, LT4 injectors and HP pump, 76mm BW S400E turbo, A2A intercooler, changed sensor config and running 3 bar TIAP sensor and TCIAP sensor, no cats, 2900rpm stall tq converter.
Attaching tune, stock tune and log from today. Hoping for some good ideas on what to try next!
