My previous regulator died & the pressure went so high it eventually blew off a line at the firewall. Put the new one in & it reads 32-33/39. Runs fairly normal (a little rough idle when cold) but smooths out when I disconnect the vacuum line to the regulator & the pressure jumps to 39. I kind of figured being off by +3 lbs was probably due to tester inaccuracy, but now I see it may not be. At least now I can troubleshoot the rough idle problem without thinking its the regulator.
