You may need to do a VATS relearn. This can be done from the Scan Tool using the DVT controls.

Alternatively you could try disabling VATS just to verify that the vehicle will run.

well we unhooked the battery cable for 15 minutes and i did a master reset with the stock tune( thick red arrow) and if cranked up and ran fine. i then loaded the new tune on there and it went on without a hitch. now im having a problem with the trans limping at 85 to 90 mph. it seems that it is a speed sensor or something. the truck is not running out of fuel because the tune isn't that powerful? any suggestions as to why?

if that is the speed that the 4-5 shift is occuring, then it is the usual allison torque slip limp.
