Hey all, a little while ago my truck was in the shop for service and I did not pull my tuner out. I didn't think that my mechanic would reflash the pcm or do anything that could damage the tunes but i was going through the stages recently and it is feeling different than before. I have been using 60tow since it feels the smoothest in shifts and the turbo will still boost. My stock tune is completely gutless and the 80econ tune feels slow, like very little turbo and only boosts around 10psi when im getting on it aswell as not boosting while on a grade. It just does not get up and go like it did before and the transmission shifts really hard. I might just be thinking it felt different because was at college and without my truck for a month. As well as playing around in 140 a bit.

Could it be possible that my mechanic has done something to mess with the chip? I know that the ford dealership could do something but everytime it goes there i pull the chip. Can a chip be tampered with while on the truck? How does everyone's 80econ tune feel, and how does the truck run on 80e? Is it possible that the 60t and 140a are fine while the 80e and stock are messed up? I might just be paranoid something is messed up but with a fresh transmission in there and i don't want to create problems with the engine either. Thanks.

 

If the dealer reprogrammed the PCM with the chip in, it would have zapped it. I have not heard too many cases where it didn't. I would take it out, send it back to us and have Jody take a look at it.
