Will a 6.0 4l80 swap run on a 4.8 tune
I'm just about to start the swap and was wondering if I can start the motor to get all fluids full and everything doubled checked before I tow it to the tuner.

I woukd see if your tuner can reflash the pcm with base tune if you bring it to them, save tow bill!! sometimes they will aspart of tuning process... I didnt swap transmissions but truck idled long enough in gear to back it out of garage so tow truck could pick her up.... I was cut short on the space to work on it so i had to have her towed to work to send pcm out for the initial tune and then drove it two hours to tuner.... Was not paying the tow bill for that one much cheaper to fill my boys gas tank to follow me there!!!
