I am real pleased with my recent turbo upgrade. When my lift pump went out I replaced it with a FASS 150 & while I was at it dropped in an ATS exhaust manifold and Industrial Injection's Phat Shaft 62. It is so much easier to maintain speed & proper RPM and EGT's. My temps are lower even with the TST running on a higher setting. Additionally, the slight amount of white smoke at cold startup has disappeared. I have gone 8,000 plus miles with this new turbo so far and 98% of the miles have been while towing, wish I had upgraded sooner
