Buddys superchip
#2
They didn't have the Hemi in 02. If he has an 03 hemi, assuming Superchip PN# 3815, he would have to return his truck back to its stock program in order to unlock the programmer and then you would be able to use it on your truck, however, both trucks couldn't be programmed at the same time. If he wanted his tune back you would have to return yours back to stock. I hope this makes sense, lol.
