Coming from a 140 hp TDI I was very happy with, I naively thought that this TSI 150 would take my golf7 into another dimension. Big mistake. I guess I don't have to explain to you how flat this little 1.5 is. Well, WAS flat because with your chip, it's really really better. I would be curious to compare with a reprog but the fact that the box intervenes at the intake and camshaft level certainly contributes to the comparable efficiency you can see in the numbers. Can you confirm? In any case, the sensations are there! There is no comparison with the other brand's box I bought before yours, which was much cheaper but which was a real scam !!!
