Hi guys Can any one give an opinion on weather these tunning boxes you can get wich state they give up to 25BHP and better mpg really work or are they just another ebay scam ??? Cheers guys Golf 4 GT TDI 115
think they sort of work, telling ecu to overboost....correct me if i'm wrong. remap of ecu is better bet.
yeah thats what i figured will be getting it remapped soon but was just wondering for a short term thing ! Thanx for your advise mate Ben
