hello I am new to tuning and am in over my head but this forum is helping quite a bit,

what I have is a 89 chevy s10 4x4 extended cab with a 88 5.7 tbi and a 91ish 700r4, that is set up for a full size truck, speedo is always off, rebuilding the 700r4 that came with the truck the ecm is the 1227747 and prom is amur. this thing has been running rich as hell(BLM108) attached datalog if anyone wants to look at it.

it was a nice looking truck until it ran me over, had to replace the door and still have a few dents that haven't been repaired

just purchased a programmer and a uv eraser, eraser won't be here for another couple of weeks. have a couple of chips waiting to be erased.
