My truck is setting a SES light when I switch to the stock or high idle position. What would cause this? It goes away if I switch back to any of the other positions. I have had my chip for about 2 weeks now and its done this 3 or 4 times. Thanks.

You're using the same exact calibrations that hundreds of others are using (PMT1 standard calibrations)........ :shrug:
The ONLY thing it could be is that there is a code setting in a higher HP calibration where it's disabled and when you go back to stock (high idle is also a stock program), the code is no longer disabled and turns on the check engine light. If the engine doesn't stumble or stall, it's not a calibration problem. If you can find out what code is set, it would help.

I'm thinking it might be the overboost code? It only seems to do it after I run the truck hard and then switch to stock or high idle. I'll have to see if my Autotap software can pull the code on this truck. If I can get the code I'll post it up. Thanks for the response!
