Got the programmer 2 days ago and have been running the 85 performance. It is just want I was looking for. I did have 1 prob yesterday. When I went to fill up the fuel gage would not move and the low fuel warning kept coming up
. I had to put the truck back to stock program and disconect the battery. After that it has been fine. Hope it was just a glitch. I am over all very happy so far with the service from PHP.
