I've been looking at DPF Removal and re-maps and trying to make the sums add up.
On my 159 1.9JTDm TI I'm currently getting 33.4 mpg on my standard mix of driving [the same motorway route to work for three years now and having played with my driving style I know that it doesn't vary that much]
Say I considered a DPF removal and re-map , or a re-map only, at a cost of £600 + VAT, or £300 + VAT respectively (AHM), and they gave me 10 mpg more, or 5 mpg more each, then the pay back time based on today's diesel prices would be 16,168 miles, or 14,288 miles respectively. If the mpg improvement were half that at 5 mpg and 2.5 mpg, the payback is 28,576 miles and 26,696 miles respectively.
So the big question for you lot who have done the mods, is what MPG improvement are you getting? I don't care how accurate so don't fuss about brim to brim blah blah...just give me the pub figures please; cost of mod (who, what, where) & mpg improvement (before and after).
This isn't a scientific study, just enough to work out how much I really want to spend the money. Those Alfacare/AHM afficianados can go to town in this thread, I don't mind the sycophants
Oh, and I haven't factored in the on-going increase in insurance premium and transmission wear-and-tear, nor the on-going benefit of not maintaining a DPF, so let's not get too excited about accuracy, eh?
