A little help, Golf Mk5 GTI

[pupiilov]

Hello,
I have a Golf Gti, with stage 1. The car slightly overboosts, throwing a P0234 error. Mechanically, the car is perfect, new N75, PCV, no broken hoses or anything.
Reflashing back to stock the car no more overboosts, and just runs perfect.
I have read that you can lower/raise KFLDIMX map for this problem, but my Winols skills are not that advanced. Maybe a good friend can help me.
Thank you.

Ok, so I tried playing in WINOLS with the map, and I made it worse(low idle/high idle, more boost cuts). It's clearly that I have much to learn...

Can you please help me with a good stage 1 map? This map clearly has major issues :(
The car is a 2008 Vw Golf MK5 Gti BWA, manual gearbox. I have attached original file.

Thank you so much.
