Hello!
The problem is that I'm seeing aprox 1.5 turbo boost pressure (2.5
absolute) all the way to 5500rpm and I can't get it to 1.8BAR. How could I
resolve the problem and what's the limiting factor of boosting max to
1.5BAR? - can one get 1.8BAR with the standart WG spring. Do I need the
stiffer WG spring (one from 034efi that says 1.9Bar max boost) or should I
fit a MBC between the WGFV and WG and keep the stock WG spring?
P.S. I have a 3BAR MAP so no worries about how the ECU could stick with
these boost levels
