Hello all,

I have somewhat of a pickle happening right now. I have upgraded my TMAPs with 3.5bar (N20) and since first start I have issues.

Obviously, I enabled the N20 fonction in the JB4 settings before starting the car.

First start was hellish, got multiple codes for both TMAPs including a short to ground signal, extremely rough idle and engine died... restarted and idle was ok, so I cleared the codes.

Let engine idle for a couple minutes and drove about 10 minutes after that while taking it easy and ramp it up to more throttle. But I get rough acceleration if I push it a bit more than regular driving.

The pickle on top of that is that now, I don’t have any boost displayed on my JB4 screen and the u/o boost dial always displays a negative value.

Can’t figure out anything about this, need help!

Thanks 🙏
