Hi I recently installed the custom stack tune you sent me and it generated a P0602 code, ECM programing error. I returned my truck to stock and then tuned in tow stacker tune and got the same code after a few starts. I dont remember getting this code before downloading the stacker tunes but I did have a dealer reflash to get get rid of the battery temp sensor retionalty code; I did return the truck back to stock beforehand.

My truck is an 04 manual 5spd calid 15235130AH is the p0602 code ok? Also when I reset my truck back to original it erassed my custom tune group; is that normal?

That code is normal while you have the program in the vehicle it basically tells you that the pcm has something edited in it. It only happens when you have a tune in the vehicle.
Yes whenever you set it back to stock it will reset all settings, including custom tunes.

Thanks for the quick reply, even on a Friday!

I'll reprogram and try it out this weekend.

Thanks again,
John
