who tuned this thing?

why are you still running a botched timing map?

sounds like maybe just a bad tune...
I have not tried unplugging the O2 sensor...although it is running closed loop.

The Affordable Fuel Injection guys tuned it several times....but they couldn't seem to get it right and stopped providing me any service. I gave them every bit of the info they asked for before even ordering the kit and provided multiple data collection files exactly as they requested, but apparently they were too busy to provide a finshed product. I would not ever recommend them to anyone ever.

I strongly suspect my timing match is botched, but I don't know how to fix it.

I consulted a guy here locally that could burn the chip...but he didn't seem to have a lot of confidence in the timing part of the equation.

I don't drive the truck a ton...so a few days might only be 50-100 miles...maybe even less depending on what I'm doing.
