    Default Stock truck idle problems after flash..?

    My cousin has a 2003 chevy silverado 6.0L that I just registered and read his PCM. I didn't change anything related to idle (or so I think) and now it idles way to low in gear and wants to stall. I tried bumping up all desired idle speeds 125rpm but the truck doesn't respond to the changes. It will idle fine for 10 seconds at the speed I want it to idle, then it will drop off and start acting funny.

    Another issue I have is that I get 'Reduced engine power' every time I reflash the computer. I clear the code and then its fine..Never had a problem with that code before EfiLive. Any ideas?

    I have the stock and modded (should show everything I changed) file attached. Please advise, Thanks.
