First tuning, hopefully someone has already made a file

[Rock.black.sheep]

I took the file posted above and changed it for the injectors you have. I also assumed the following:

- You are using the original truck MAF sensor.
- The wiring harness and tune you are originally using were set up for a 4L80E.
- You have the fans controlled by the PCM.
- The A/C fan control is done by the PCM.
- You are running E10 pump gas.
- You deleted the catalytic converters and EVAP system.

You could always just copy the injector values over to your current tune and go from there. The tune I set up is assuming that the wiring harness is set up for a 4L80E and I've already changed the transmission shift tables and torque converter tables to account for your rear end ratio and tire size.

Thank you, that's great! I am using a BP automotive harness, the original MAF, fans are PCM controlled, and cats are deleted. The file I uploaded should be my existing bin file, and I will be loading the one you modified in the car shortly. Sorry I'v been slow to reply, I have family coming for turkey day and I'm trying to get the house ready
