Before I head out and try this I wondered if one of you more experenced tuners to look this over to see if I am on the right path. I have a 02 CrewCab S10 4.3 auto, k&n drop in w box cut, corsa exhaust. Daily driver and wanted to make some changes..ie firm up shifting, maintain or improve MPG, not much trailer pulling.. I may either make a second tune with "tow and haul" parameters later but I am trying to get the feel for this. Also if you have any Histo's or help with what I need to be logging and watching in my scans for the transmision. Thanks
