2008 6.7 P0106 code!! please help
 

Hey Guys just pick up my first 6.7 Cummins coming from all power stokes in my past, The truck is super clean has all deletes and Mini max. Truck has 140 on the clock, I use it to pull my 24 ft enclosed race car trailer. Since I got the truck it keeps tossing a p0106 map sensor code. I replace the map sensor today along with a new turbo speed senor also put a new Sb cold air intake on it as the last guy has the wrong intake on it look like a 5.9 intake lol. Still I clear the light and then it comes right back and truck goes into limp mood, I am really running out of ideas. any insight would be great, truck had a smoke switch at one time could it be if it still powered it dump fuel somewhere and a sensor is getting a false reading from that? please guys I need to get this truck back to being able to pull asap!!

Thanks!!!
