Got my Intune today first time ever using a tuner took some time getting it to sync up with my truck with help from diablo got it to work. so i begin to load up the 87 tune all goes good tune is loaded. start up my truck and go for a test run well i made it about a block from my house and the CEL light comes on and it seemed like my trans wasnt shifting truck felt really weird. So turned around hooked intune back up and ran the code for got the code but is was something to do with the trans?! I cleared the code and immediately loaded back up the stock tune. Everything is fine now. Any reasons why loading 87 tune would make my trans act up within minutes of loading it on?
