Can someone recommend an excellent diesel mechanic that works on 6.0 that can do upgrades? As in bullet proof and do a few other custom tweaks to it.. Not looking for a backyard hack...if you dont have your own tools or a shop to work in.... dont bother. . but I dont mind someone that does side jobs. Someone that is reputable and stands behind their work.. A custom shop would be great! Any info would be appreciated :) Thanks! Added-- its a 05 F350 Crew cab long bed 4x4.
