Just dropped off my 57 140 tdi with stage 1 revo for it's service. My car should be pushing out something in the region of 185bhp and a good few torques but compared to the 140 cr tdi i just picked up as a courtesy car mines is like a snail!! The new engine is so smoth in comparison and revs all the way to 6 grand with no real drop off in torque. I cant believe the difference between the two, going to have to trade mine in sooner than i thought!!
