I am testing my 98 5.7l vortec

I have 60psi after priming pump. Then it drops down to approx. 55 psi after shut down.

Does the pressure leak down any further? I still have approx. 55psi several minutes later.

Thanks for your input!!

  PS: Here's pic of the 2014 wheels I'd like to run when it's not winter. Stuck my finger around new wheel caliper setup. Very little clearance. I suspect these won't fit, but won't know for sure till I try. Edit: And my first mod. Stubby antenna from the old truck.

  I bought it today and brought it home. They still owe me the bed liner, remote start, and they also agreed to get me the flat black bumpers to replace the optional chromes ones. While some folks may think I'm crazy, I think they'll look a lot better with all the other black stuff. Blacked out grill, mirrors, running boards, dark essentials Chevy tailgate lettering along with the black Silverado and Turbomax emblems. I do want replace dark essentials Chevy front grill emblem with the base level gold one. The 2.7 4 seems to run well and push a 1500 along just fine :).

  I did plug the vacuum line and the rpms where ok. I also tighten the booster line going into the intake. It was a bit loose and that didn't make a difference.
