i had high hopes for this product
i had high hopes for this product. up to 47% less fuel usage.
but no they say many of our customers get good mileage if u buy the 400 euro ecu also. no one reports any good mileage but them self's. it may be that the computer says that u use less but when u fill it up the fuel usage is the same. i have driven for 6 tanks full no change. SCAMS
