Guys...thank you so much for helping me out to find out what is going on.
The graph didn't also looked like to me as well having a leak (seems prety steady in terms of boost level) but considering the boost gauge reaction i was really thoughtful

Although the engine will not see the boost spikes while you shift - in case the throttle is closed causing the spike - they seem to be quite high. Using a flash, I currently never spike above 16.5 PSI while shifting ( it's cold here outside, winter season ). Do you see +20 PSI spikes on the gauge as well, by recalling maximum boost ?
p.s. does not look like you have a boost leak, IMO.

I have one of the very first versions of Rixt3r boost gauge. I never see spikes more than 16,5 to 17,3 (only once or twice, ever). I used to do calibration with the engine completely cold (and shut off ,of course).
Its very cold here as well (for our standards) between 5-8 degrees (i'm serious! this is cold for us
).

You didnt scare me...it was just the cherry on the pie as i was also very sceptical due to boost gauge reaction.
