Hi , can anyone shed any light on the subject of fuel economy, my '02 magentis SE 2.5 automatic has just done my regular 200 mile round trip for the first time and Im really **** off to find that it only averaged 29.odd mpg. My old 4.0 sovereign did 33mpg on this run as did my old 3.0 24v senator. Im talking Imperial gallons not US. around town its even worse and I'm too scared to use the tiptronic box to get a bit of go out of it in case I hit single figures !! How easy is it to reprogram this engine/tranny as I would like either economy or performance, at the moment im getting neither !!! I quite like the car but am disapointed by the fuel problem, any ideas ?
