Hmmm. 37-43 psi with the vac line on at 10.6:1 compression? Thought that was kinda low.

yeah it is about 40-43 psi with the vac tube on a usdm engine. might want to bump it up just a tad for the 10.6 compression.

its the same as USDM engine. no difference, .6 in compression makes no difference in overall fueling the point where totally differnet fuel pressure or maps are really required.
