Hello Everyone,
I have just purchased a HP mpvi2 tuner, mainly because I am removing the clutch fan and installing dual electric fans and running them off of the pcm, also to adjust my tire size to correct the speedometer.
I am new to the interface, as my last tuner had basic options for performance levels.
My 2001 tahoe is a stock 5.3, 285/75/16 tires, 3.42 ratio rear end, and I have a cold air intake.
I would like to tune it to run as good as it can being stock..
Any suggestions are greatly appreciated.
I have figured out how to activate the fans and change tire size and have currently changed the tire size.
