so at the moment i have a6 turbo convertion, decompd, runnign standard na fpr with turbo injectors, and na ecu, (how it was when i got it,) do obviously it running rich as sin, Ill be getting a turbo ecu for it tomoro hopfully, and was wondering what i should do with the fuel pressure reg, weather i can leave it or will it lean out, i have a malpassi to put on it but ive been told there not great, or will it do in the mean time untill i get get ahold of a turbo FPR,

Ive had a malpassi for over 10 years and haven't had a problem. As long as it's a rising rate one I dont see what the problem will be..

Turbo and N/A FPR's are the same. Only difference is the mounting bracket.
