Attention: TDR Forum Junkies 
I just left a local Dodge dealership after talking with the diesel mechanic there. I brought up the topic of high performance and he really perked up. He wanted to sell me a diagnostic tool used to check the MAP sensor that just tells the computer you have full boost all the time. He wanted $100 for it. He went on to say it wouldn't void the warrantee because it didn't allow more power. He and the service writer told me you could just take it out before coming to the dealership and there wouldn't be any problems.
He then started in on 'black boxes'. I asked him what signs he looked for when working on one to check for performance modifications. He said usually people leave the velcro on the fuse box where the boxes are mounted. He also said the pump connection (VA style) usually has fresh fingerprints on it. I argued that fingerprints just mean the connection has been touched or removed. It doesn't actually mean a box was installed. He said when he sees velcro, or fingerprints on the pump connection, he writes down the engine number, vin # and sends it in to cummins. He told me that if the truck is brought in for engine failure, cummins will deny warantee work it.
He didn't say he checked for pricked wires or wire insulation damage in any way. He seemed to be under the impression that the only 'black boxes' hooked up to the pump connection like the VA does. I didn't want to tell him about other boxes, so I just left well enough alone.
It upset me that he sells a boost fooler and tells his customers to take it out before warantee work, yet he sends in vin #'s with only the slightest hint of a box being installed.
It seems to support his own business of boost foolers quite well though.
Beware guys,
Chris
