I was tuning my truck back to stock the other day and noticed my PPE tuner runs diagnostics, and had a specific diagnostics screen for the injectors.

is there a way to run it while the truck is running, and/or without taking all the fuses out?

yep just plug it in well running and go to the diagnostics screen. as long as you dont try to tune it there are no issues with it.

The only fuses you remove are the radio and the info-- they don't affect anything.

Of course if you don't remove the info-- On-Star will have a recording of you messing with the computer. ----- Just Kidding.

The only reason they ask you to remove them-- they don't want a sudden change in the voltage, when loading a tune. That is why you should have good fully charged batteries, and do not open doors, or turn anything on or off.
