Replying to: jeepboy08 (Jul 29, 2008 7:07 am) Yes, this is only for CRDzzz You can re program the engine controller not to react to emission control sensor values (understand the EGR system with it's butterfly valve and the two Lambda sensors), the gearbox shifting sequence to reach 4000 rpm instead of 3600, etc... If you floor the throttle pedal while in Neutral, the engine will rev up to 4000 rpm. When a gear is engaged it doesn't go above 3600. Without the EGR messing up performance, this tranny shifts and locks it's converter really fast. Mine reacts to the pressure of a toe
