2016 L83 5.3 Silverado
Stg2 cam, Whipple, LT4 pump and injectors
95mm Soler throttle body
Is it possible to tune this combo? I am hitting a wall! Can't make it idle how I want it, hangs throttle on decel.
There is no throttle body flow calibration like on Ford or Dodge.
Changing max throttle mm2 does nothing.
Pulling air to close throttle (via maf or VE) - bugs off the torque and fuel calculation.
Fooling torque tables makes AFR and timing go haywire.
Decel is possibly hardcoded to 26% - which makes this combo hang at 6300rpm.
Current tune attached. I have tuned same combo with stock throttle body and was done in 2 hours. I have been fighting with this for 2 days.
Please help.
