Sorry Rich -- missed this one among last night's messages. First: Have you ever driven another D for comparison purposes? PRV more than adequate, but isn't going to give you whiplash. Could simply be expecting more than it will deliver. Even new from factory was 8 plus seconds 0-60. Second: Ensure your CPR vacuum and Lamda full throttle enrichments are working. DeLo runs fairly lean otherwise (European CPR 8.5% richer than US import). Do you still have borrowed fuel pressure gauge? Third: Don't roll your eyes -- why not temporarily bypass Lamda? What do you have to lose? Only need a single banjo bolt for the return line and an 8x1mm to keep trash out of lower chambers. I have a spare 038 series CPR you could try too. Would then be metered basically like E series rather than F. (BTW: If you try 3rd option and like it, would appreciate a post in big capital letters retracting all the grief you emission boys have given...)
