Your answer is as close as your UPS store.
Jody Tipton (DPTuner) reflashed a spare PCM for me with his 80Econo tune.
I forgot what tune it had originally, because it does not matter.
Jodi wipes out the previous program and starts with the Ford PMT1 strategy. He then modifies it to his/your liking.
I don't know how you feel about the way your truck drives now, but for me, it was like going to a big block gasser. It has MUCH better throttle response, the shift points are spot on and it is generally more pleasant to drive.
Do not wait, do it now. You won't regret it.
Best of luck,
Bill.
