mine has a brand new sensor in it but no change so I changed the limp tables in it for now. it still says reduced power but doesn't actually go into reduce power. took a little to find all the tables but it runs fine but I want to get this issues resolved and put the reduced power ability tune back on the truck.
Try the one I just sent. If it does not work I would try a different OS and / or take away the rumble idle.Originally Posted by chevyman2

at this point it's working time will tell. I didn't even think about changing that stuff thanks!
My pleasure!

boost.. my brother is having problems with his maf on his 08 duramax all he has done to it is dpf delete and egr delete.. I used my efi live to disable the dpf and egr in the computer but is still having reduced power and throwing maf code
Sounds like you overlooked a limiter or a temp enabler. You can't just shut the codes off as this won't always work. You can stop the codes that way, but the ECM will still go to enable them. And just setting them to disable doesn't always work either.
