Mod friendly 6.0L dealer?

[Rob.D]

I'm on the list with Spartan Diesel Technologies for there upcoming release Phalanx tuner. I'm not looking to turn my truck into a hot rod or beat the crap out of it. Just looking for a modest increase in fuel mileage and eliminate turbo-lag. I'm still under warranty and dealerships really vary with opinions on such tuners and honoring warranty work. My biggest concern is lifting the heads which is common with the 6.0, tuned or not tuned. Anybody have a favorite dealership that's treated them well. I'm just north of Grand Rapids. Mod hater's no need to reply. Thanks

I don't know of any but I am not familiar with any of the dealers in that area. If you ever need a good mechanic down the road I know a good mechanic that drives a big black 7.3 and lives in Silver Lake.......LOL
