Hello all,
I have a 03 5.3 with P59 ECU swapped into an AMC Gremlin. It has a stage 2 Summit turbo cam, valve springs, ring gap, Deka 80's and a 7875 turbo. 4L80e transmission.
I am running 2-bar SD no MAF and no 02 sensors. I am exceeding the 1.20 g/cyl around 2 pounds of boost and have no more timing control.
I know there is a method to scale Injector Flow Rate and a bunch of other charts. Does anyone have a better method for accomplishing timing control rather than the scaling? I read that i can run into automatic transmisison shifting problems due to incorrect torque calculations if not done correctly.
If there is already a writeup on this please point me in the right direction. Any help is appreciated.
