Tuning for more MPGs

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...

You need to log Cummins PID's...you were logging what looks like GM PID's.

I ask my customers to log these PID groups....please select the green check marks in order from BOTTOM to TOP. You will get a error message but ignore it.

Relog with those PID's and the help will come.

Les I am trying to set up my PID Group it will not let me get all 4 of the group with green check marks. http://img.tapatalk.com/d/12/11/04/3uzu2ygy.jpghttp://img.tapatalk.com/d/12/11/04/avyjujev.jpg

Yes that's the error I was talking about...continue on and it will not log a couple parameters but will log the necessary ones...

Took me a while of trial/error to get the order and number right to keep the right ones and have the unnecessary ones cut off.

You MUST select from BOTTOM to TOP!!!

Yes your right I see them, but how you get all 4 check marks to stay green not one red and three green. Will it correct to all 4 green after I loghttp://img.tapatalk.com/d/12/11/04/uheru9ez.jpg

Not sure..try it and see.

It works Les big thanks

If the OP logs with those pid groups...help will be given.

I just haven't had time to really play with this truck...
