Is freightliner the cheapest Dyno or can Someone else diagnose my power loss issue

Did you check for boost leaks?

With any kinds of forced induction, the very first thing they will do before strapping the rig to the dyno is check for boost leaks. If they do it, it costs big bucks for what could be such a simple fix.

 

There are all kinds of places that do Dyno's, call one of the dealers around and thy should be able to give you the local dyno shop.

 

Bad idea going to the dealer/manufacturer dyno. They will have to burn the goobermint tune on your ECM.

@superhauler, can you verify?

 

Yeah, it’s true. He would have to find an aftermarket shop like Performance Diesel or Pittsburgh Power to get a good tune. Goobermint tune will compromise performance for a treehugger happiness tune.

 

Just to do a dyno, they shouldn't mess with ecm. Just tell them to NOT flash it. Verify this before any work is done ! If they insist, drive away.
