Hi! I resently bought a golf mk4 1.8T variant and i just got it mapped. Stock it made about 0.5bar and with the mapping done its now peaking between 1.7-1.5 bar wich seems like way to much? I got the AUM engine code so should be the k03s turbo but can only ser People boosting max 1.4 bar with full exhaust, but mine is all stock exept open airfilter

Limpan,
Congratulations on your new car! I believe that your boost is fine. What are your concerns? I am running a K04 Turbo with APR (93 octane) software , 3" downpipe, competition cat and full 3" exhaust on an AWP. It boosts a total of 28 lbs (@1.9 bar) and holds it quite well. I have been running this configuration for the past 10 years for over 20,000 miles with absolutely no problems. Enjoy the Boost!

Thanks ? i Was just concerned because i don't know how stable the k03s is at that kind of boost, some People say that its getting ineficient and well i'm a little bit concerned about the engine aswell ? the biggest concern is the flutuations between 1.5-1.7 bar but im thinking of buying the n75"j" Valve but its expensive ?
