Is anyone able to advise the difference (mechanical/electronic/gearing) between the 70, 75 and 80 bhp 1.4PD Fabias. I am currently running a 70bhp and wondered if anyone had chipped one. At first I was doubtfull of getting what is basically the bottom of the PD range, but up to now cannot fault it on my daily 22 mile drive over the Pennines.

I just recently got myself a 2006 Fabia 1.4 TDI 80, and just yesteday got it remapped. The guy said it should now be at 105bhp and 200ft/lb torque, can't really complain

Anyone able to give the details of the differences. Still enjoying it having averages 55.3MPG over 17.5K miles. Just looking into a Blacksmoke remap.
