Boost presure losses on 5th and 6th

[mihai]

Hello all! I own a Seat Leon FR 20 VT and after i got my remap done,and I was pleased with the results, I've experience boost presure losses on 5th and 6th gear on high RPM's. Anyone have any ideea why?

the 20vt a standard (or remapped) doesnt produce boost high up, try flooring 5th gear from around 2500 revs, youll see it is there but tails off after 5500 ish.

I agree with you but my boost presure is going up and down several times in 5th and 6th gear after 5000 RPM.
