Yeah, the Bosch K-jet manual details it pretty well. Based on the manual I am going to start with 2 shims and recheck pressures. Current system pressure is 4.3. Per the manual 2 shims should raise it by about 0.3 bar. Before I do that though, I’m gonna check out the remaining components of the fuel system now that I’m this deep into it. I checked the fuel pump volume earlier this morning and that was right at 850 cc in 30 seconds. I also checked individual injector volumes and they we’re all within 1-3 cc of one another. Still going to check the cold start valve to make sure it is working properly/ not leaking.
