I am tuning a friends V6 pickup and after running through and tuning the shift points, the Tow/Haul no longer comes on. This is one of those older style pcms where the performance mode tables are not there; Economy is there instead. Also, when changing any data in the Force Motor tables, (positive and negative) the truck reverts to max line pressure (0amps/96%). The other problem we have, even when reloading the stock tune, is that the truck will crank and spin over but not start unless you give it gas, and then it will idle and maybe 2 times out of 10 it will die. I have scaled the top right hand corner of the VE to help with this, but I know that is not a good cure and shouldnt have to do that. Is something odd happening, or is this common? The latest tune file we have is attached, as well as the factory file
