Seen a few video's posting about 'Racechips' and claiming they are going to get increased performance and economy. They use predefined maps that arent custom for each car but are custom to the model, the main thing to me is they are less than half the price of a ECU remap from a local professional. Supposedly get +16Hp on my MkII 1.5 Dci, wondered if anyone had any experience with these?
