So iv seen this plug and play remapper on fleabay ;
OBDII Soft ReMAP High Performance / HHO EFIE / 18% Fuel SaverChip BMW E46 | eBay
Now its got me thinking, is this another scam promising fuel efficiency and more power for my money and delivering nothing or could this be a worthwhile investment?
Im wondering if anyone on here has come across this or a similar product that could give me any advise.
Im think someone will confirm my fear that its a load of rubbish but theres still a glimmer of hope..... lol
