Tune question

[04rcmoneypit]

I disconnected the negative battery cable to clear a AIT code and now the truck sounds completely different. Throttle response is bad and I am afraid to even get it out on the road. Is it possible to loose a tune by disconnecting the battery?

Nope, the tune is stored in the PCM like a hard drive. Do you have any codes? Cycle the key from off to run 3 times and report the codes displayed. The PCm also has to relearn after battery removal but shouldn't run that terrible at all.

Yep, had a p0113, which I looked up on here and it is a AIT voltage too high.
