Wow 1.35 bar! OK I am fairly new to the 930. but it seems to me that you definately need to get that boost down. When I installed my GSF headers I was around where you were with a 1 bar spring. I found that I needed to go down to .7 to get my desired .9 bar. As stated above it is probably a real good thing that the turbo is running out of breath. Once you get the fueling sorted out and possibly a more efficient turbo. that motor is going to be hurting at 1.35bar and have much bigger problems. yikes! Just my .02

87 930
