I'm still learning, so bear with me... trying to tune a friends truck for maximum MPGs. It's a bone stock, right down to the air cleaner and exhaust, 2006, Quad Cab, 3.73 geared truck running 265/75R16s.
Since I'm still learning, I started out with the "gift tune", backed off the main injection quantity a little, increased the timing in the 1500-2200RPM range a litte and this is where I'm at.
One thing that concerns me is the balance rate of the #1 injector, it seems to level off at -2.2
Looking for feed back...
