Ran 5/32 tubing from engine intake forward to the new 30# gauge . Test drive . Saw max boost of 17/18 psi on new gauge , dash reading 9 or 10 . So I'm thinking the boost levels are on par with other mechanical 8V92s .
Now I check the new Filter Minder and find it at 20 inches , almost max . Air filter looks good, but must be time for replacement.
