Excellent diesel service shop, wish they were closer to Chandler! After extensive internet searches for an OBS fuel system upgrade the driven diesel complete fuel system was hands down the best in my opinion. Along with a turbo rebuild, a complete upgrade of the HPOP system a DP tuner and a John Wood tow master transmission my truck performs great! The service I received was second to none, and Gary and Keli were a pleasure to deal with. When my next upgrades are due I will not hesitate to make the drive to north Strictly Diesel.
