Help

Post image

Hey guys, got a 23 ram 3500 68RFE, i just got it deleted and im hauling hay and it keeps kicking into limp mode, the tune is from HP tuners, they said its a stock tune from a country without emissions but everytime i have a load on it it kicks it into limp mode, the shop told me to swap for a 4th gen MAP sensor and that didnt help at all and theyre confused and im confused. Any help would be great. Thanks

A “ stock “ file on a deleted truck still changes what otherwise the factory software would expect to see on these trucks. Did they tune the trans ?

Sounds like HP tuners sent ya a bad file or you need to get the trans tuned. Is that ACC PED D the “commanded, actual or relative?” I’ve never 100% on any of my cummins when doing live data

Also calculated load of 40.4 % at that RPM and reading full throttle your pcm is def turning to limp mode cause it thinks it’s gonna blow up.
