Have you tried using the 3bar MAP sensor as fitted to the GolfR/S3/ED35 motors?

That's right, I already have the 3 bar MAP sensor for my K04+ tune.
I noticed the car has been driving strangely ever since my throttle body pipe blew loose under boost a few times.
And, since I have checked almost everything, including pulling my K04 out and reinstalling it, new O2 sensors, new spark plugs, new fuel filter.., I suspect the MAP sensor or the MAP sensor harness may be damaged when the throttle body pipe blew loose.
I am on the cusp of trying another tune, because I flashed back to an earlier version of the DM K04+ and the car pulled much better in the low RPMs. I am experiencing very poor torque under 4,000 RPM, but right when 4,000 RPM swings around, the torque instantly kicks in, and VAGCOM shows that is when the timing advances above 0 too.
The car seems to drive significantly better at night vs. during the day. If I think about it rationally, I think the MAP sensor harness is more fragile than the MAP sensor itself, so that could be a problem. But, I checked the MAP readings while wiggling the wire, and couldn't find any changes in the values. Could it still be faulty?
