Tune is by MTM out of Germany, not sure how I got my hands on it in Canada as I bought it 2nd hand out of the USA.....well travelled.
I figured out the "blank" code after sparking up VagCom, it was used in an Auto car and mine is 5spd, soft coded it to 5Spd and the TCU code(which was the blank code) was cleared and stayed away.
Still have the "surge" boost thing happening, next up will be a fresh N75 boost control valve and upgraded DV and new plugs. I also have a code showing for a bad 02 sensor(heat circuit code bank 1)
I have a feeling the tune is set for 94octane fuel as well and the best I can get here is 91, it ran noticeably worse on the 87 I had in there for a bit.
I may end up swapping the oem tune back into the car until I get the required parts together to take advantage of the full tune.
