Anyone big into the larger diesel engines, know of a tuner or something to do to this engine to get more power out of it? Everything I've looked at says not much help unless you want to spend big bucks.
I am not aware of any hi-po mods for the "E" series DT466. The days of adding some fuel with a screwdriver are long gone... Depending on the HP rating of your engine their may be some different programming available from the dealer, but that is a real long shot. In the meantime, make sure the engine is running as it should. e.g. Proper amount of boost, correct fuel pressure, etc.
A different approach would be to start planning a 3406 or N14 swap.
Call your local IH dealer with the last 8 of the VIN. Depending on what HP you have now sometimes it's possible to get more from a computer reflash. Never heard of an aftermarket computer or chip for them (ie. BullyDog)
Thanks guys one dealer said not to much they can do, TS performance has a plug and play tuner 30% increase in horsepower. It has mixed reviews from some of the diesel shops I talked to they said some people liked and some were less than impressed. Waiting for a call back from another company will keep updates here if I do something.
