Porsche did a pretty good job selecting a CPR for the 930. it has control well beyond the factory tune. It also has a press fit pin that you could carefully measure and adjust pressures but it is a bit complicated unless you mod the pin. Everytime one of those things come into this shop the afr's are whacked. I run the stock CPR and boost at 1.2 bar with near perfect afr's. the only non-stock item in my fuel system is the two 044's. Too many people use this BL unit and there is something else wrong. I'm straightening an 89 out in here today and the client wants to retain the BL unit although I couldn't get it tuned right. I swapped a brand new CPR on it yesterday and tuned the mix and it was almost perfect for the little time I spent on it, but he wants the BL back on today. These cars are easy to mod, headers, turbo etc. but with solid tuning, the simpler the better.
