OK i have a 07 silverado ( classic ) 2500HD i have saved my stock...
I finally flashed it who hoo... after about an hour of idling and revving in my shop i took it for a spin... who hoo...
got almost back and went into reduced power and shut down... said overheating... was not hot... friend pulled me home..
now i have disconnected battery over nite tried re-flashing stock to no avail.... when i run vcm scanner it shows tps at 100%...
here is the question... if i buy compatible junkyard pcm can i do all the flashing i need to make it work for me or will i have to order one from someone who can set vin and mileage???
preparing vcm fails. boot loader request times out....
