    Hi. I have a motorhome with a Fiat 2.5 TD engine. I was wondering if anybody had any advice on how to get a little more power out of such an engine. Im not wanting massive gains, just want to be able to maintain my speed on hills.

    governor mod... you get more fuel vs the pump restricting fuel flow at higher rpm.. there is article on vwdiesel.net on how to do this..

    be careful of egt as more fuel = more heat... and the renuot (sp??) motor homes cracked all kinds of stuff from heat... and im thinking that was a fiat engine?? i may be wrong... but a egt gauge is a good investment... my brick pushes alot of wind too... and ive been lucky on egts where even under abuse ive maxed it out at 1250*f and i was trying to get far more... but man.. what fun :)
