Ok guy I was writeing a tune on my 2006 regular cab 5.3 Pickup. An hptuners burned up completely, the interface was burnt black on both ends. So i tryed to crank the truck wouldn't rev past like 2000-2500 rpms. So i just thought the tuned was messed up. I sent the equipment back got all new stuff, an tryed to write a tune tonite thinking it was going to fix it nope did not.... I unplug battery, checked fuses what is the deal please help???

 

Do you have throttle response or does it just put itself at 2000-2500rpms?

 

unplug the battery for 5mins or so... pull the file from the truck again, and load it back in, then start...should help
