I had an 07 Silverado classic with the 4.8 for a number of years. In those years I bought the Diablo intune and installed the 87 octane tune. I have since sold the truck. I then bought an 04 Silverado with the 5.3. how do I tune this truck with my tuner?

you need to have restored the original backup stock tune to your old truck in order to unlock/reset the intune... and then you would be able to use it on the 2004 truck...

With the 2004 truck, Anything aftermarket installed in the vehicle? i.e did not come from the factory?

You need to make sure anything aftermarket is disconnected/pull the fuse for - anything like aftermarket stereo, subs, amps, nav, alarm, remote start, seat heaters, trailer brake/light setup, etc.. anything like that, their wiring harnesses need to be disconnected/pull the fuses for it before you try to tune anything...

also make sure everything is turned off inside the truck.. lights, radio, heat/fan/blower, do not operate power windows, put your parking brake on, etc...
