Does it throw out a bit of smoke if you boot it???
The SDi's will push more fuel in than the o/e injectors, thats where they give you the extra power. But at a cost to the mpg.
I had my one remapped, but still a bit of smoke.
Was getting 55+ mpg on mixed driving, but down to 45+ I reckon now, must admit not checked it.
Can you red line it, if you boot it and does it pull through all the gears. The MAF sensor can go and this will stop it revving freely. Makes it feel flat.
22 mpg seems low, I have a few fill up, receipts with miles on, in the car, just been a bit worried to work the mpg out! I'll go and get them and see what they say!!!!
