OK here goes, I have a 3.4 with 7.5 to 1 compression and a 1 bar spring in the waste gate. I have mine set at the following. 2.0 bar cold control pressure. 3.9 bar warm control pressure. 1.6 bar enrichment pressure at 8 psi boost. In addition to this i had to turn my system pressure up to 7.4 bar, and replace the front pump with a Bosch 044 pump. It finally doesn't run out of gas at full boost. Since most of the CIS gages you buy only go to 7 bar i had to get a new 0-10 bar gage for mine.
