Hello A3 community! I have a 2.0 TDI with which I am super satisfied. The 140 hp are enough for me to BUT there is a certain situation where I would like to be a little bit more for the butcher’s specialist saleswoman on the question “May be a little bit more.” would like to yell against YES – in the sprint from 0 to 100. It is not possible to leave a Golf GTI with 115 hp older year of construction properly. This one remains at most half a car length and if you screen the start easily, one loses miserable. No wonder, the A3 is also almost 400 kilos heavier. My question to the community: I would like to hang in a cheap powerbox. That should therefore not hold out for a few acceleration races only for permanent use. However, the engine has to be spared a little bit. Can someone recommend something to me? How much do I have to spend? I would like to take the powerbox from KW-systems but because of one or two acceleration races this is much too expensive. My wish would be a box that I just hang in the WE, my ego polish and then can be sold to me again?
