2nd gear, floor it: Boost, slight flat spot between 4k - 5k rpm then back on boost again. Anyone else been having the same issue? Is it anything a remap can't fix or shall I leave it?

The issue is still apparent, here's a video of it:

Doesn't happen in any other gear apart from 2nd for some reason...

Okay, turns out the possible cause is because of the Turbo Wastegate Actuator not having enough grease around it, causing it to stick momentarily. The solution is to either get a garage to remove and regrease the part or to have a completely new part installed.
I'll carry on driving with the issue as it only happens occasionally. Will have to fork out for a new part if and when the problem gets worse.

Glad you got it sorted (and useful to know the solution..)
