I just ordered propane injection for my PSD today. I will keep you up to date on how this does for me. That will make my little sentence at the sig line all the more true. The upgrade numbers are as follows. 80 HP 66% more torque (150-250 lbs) 40% better fuel mileage along with cleaner oil due to more complete fuel burn Bring it on. With the upgrades already done I will have in the neighbor hood of 385 HP and some where between 850 and 950 lbs of torgue. I will have to go dyno it when it is all on so I know for sure.
