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.
Excellent info. This is exactly what I was looking for.
Thanks so much for taking time to post the info. This should be a good starting point for me now.
