eBay - The UK's Online Marketplace
mine has been fitted for 3 weeks now and i cant praise it enough more power smoother and most of all MPG before i was averaging about 37mpg, now averaging 41mpg, should be even better when i get the injectors reconed
73,000 miles on mine np with mafBMW M47 engine as the standard MAF is very expensive and will fail at some point, anywhere between 30,000 miles and 70,000 depending.
I don't think the two are the same box, if you want a tuning box look into the Synergy, it not only offers different power maps for the engine, it offers a MAF compensator which is very VERY useful on the BMW M47 engine as the standard MAF is very expensive and will fail at some point, anywhere between 30,000 miles and 70,000 depending.
