I know that there is a big dilemma between the people decided to up their power if they should go for a remap or a tuning box. The remap is the more expensive option, but most certainly the better. Recently, I was browsing ebay for tuning box and one appears to be always on top, but there are not any review, which makes is very suspicious. Anyone having experience with this one? -
