Tuning help (Mini)

NMSVT · Sep 16, 2017

So i have been running freely at the tune of about 75k miles. Truck runs great, no issues whatsover. The other day i tried to install my SCT iTSX programmer instead of the mini just to try it out. Unfortunately, i had left the SCT in my Lightning. So i proceeded to reinstall mini and after i started truck up and drove home, truck ran way better than before! Ran stronger and faster. The next day, went back to how it was before...

Any suggestions? I have tried searching and could not find anythinng on the subject. Any help appreciated thanks!

Was the trans shifting better/different/worse? Most likely, you are experiencing the relearning of the computers after loading the MM files back in.

Trans shifts the same man. Before i re-installed tune and after. I am aware of relearning process for trans but that does not apply here. Engine performance goes up after tune re-install, its weird. Then after a shut down, turn it back up and no more power like before? Its a strange issue. If i cant find why its doing this, i might have to get some custom tuning.

If you are still running the H&S tunes then you should call Mike for some better stuff.

Phonetically 'tunning' is how those with a desire to have intimate relations with many oversized women keep score.

Yeah thats what im just gonna do thanks man. Its just odd to me that when the tune is reloaded, truck feels stronger and faster. Just wanted to see if this was a known issue or just an isolated incident. Ill look into getting custom tuning for it after my Lightning project.
