Ok guys here is the story. I took my truck to a dealership to get a full detail. Got there and the truck looks great bad parts is it doesn't (didn't) run great. I got in the truck everything was fine except I noticed my mp8 was turned up a little. (could have been from cleaning) I pulled out went about a1/4 mile down the road and the motor completely changed and got real loud the truck started bucking rpms went way up and the truck wanted to take off. I shut it down and started it up again after a little. Took it back to the dealer and it did it again luckly right when I pulled in. We talked about this for a little while and I thought maybe it might be the MP-8 because they steam cleaned the motor and it might have got it wet and ruined it. I unplugged it and the truck ran fine then for the mile or two I drove it. Could that be the problem? Would it make the truck act up like that? I left it at the dealership they said they would look to see if they can find anything else for free. I was also wondering if I have any bargaining power on getting a new one if that was the problem (although I doubt it). Any input on if that could be the culprit or if something else could be messed up? Thanks for any info.

If they got water in the plugs it could've damaged the unit

Rule #1 when taking vehicle to dealer-Remove all aftermarket electronic units. Yes, water in the map sensor plug or the fuel pressure sensor plug could cause problems. Sometimes you can leave it unplugged to try and let it dry out and then reconnect it. As for you calling TS performance for another MP-8, are you going to explain to them that YOU allowed water to get in YOUR sensors connector and that is the reason its their fault?

Reason? If MP-8 has connections that are in the engine compartment, then they should be sealed. Engine compartments get wet. That is why all the connectors from the factory are weatherpak and waterproof. I would check w/ MP-8 people. Now if your radio has water dripping out of it I would say "Operator error". Just my .02.

steam cleaning the engine while in the rig on any of these modern electronically controlled powertrains with the dozens of electronic sensors and connections is just asking for trouble.
especially if they use a cleaner additive in the steam cleaner, most are electrically conductive. that high pressure hot steam at 200psi and 300d F will cook and penetrate anything.

Dodge/Cummins only recommends using a solvent wipe down to remove grime and dust as least until the bare engine is out and away from the electronics.

Dodge uses some of the cheapest electrical connectors in the industry, little or no sealing.

what's the name of the dealership. i won't be taking any rigs of mine there.

I am not blaming anyone for this unless the guys at the dealership took it for a joy ride and messed something up but now that I think it is the mp8 I know it is my problem never was I blaming TS or trying to get anything out of them. I thought maybe the dealership might help out the way some of the managers were talking so that is what I was asking about. I never would have thought to disconnect stuff for a detail it isn't like they were working on anything. I appreciate the help guys.
