Cummins191

Runs normal when we ran it down the road it was fine we set the limiter to 4000 and it would run all the way up and have no issue until I went over 4000 and the check engine light will come on and it will start to run bad until I clear the CEL.

4 years old or so.

What I mean by freaked out is when we hit around the limiter in the quad or apply a load with high rpm the CEL goes on and the truck has issues as what the video I submitted.

Hit 3600 rpm and CEL turned on and automatically know problems but have quad set to 4400 RPM but I didn’t come close to that and it freaked out any help would be much appreciated iQuad-2021-08-07-07.35.15.csv

Map sensor solved the problem for the boost pressure being 31psi. Will provide a data log for it soon probably Hooked to a sled.

So we unplugged the map and it reads 0 and when plugged back in it reads 31psi not running and threw a map code for low voltage so I’m going to buy a new map sensor and report back with new findings.

I was not driving the truck that night but my brother said it was on number 7 and they did not test it other than when at a stand still.
