Boost gauge ?? questions

[prophecy7115]

Ok i just installed my boost gauge and at idle it read 25-30 vac in idle and slowly climbs and stops at about 21-23 vac.. and i think its accurate the gauge reads 13 pounds psi at WOT.. (with the BCS REMOVED) so i gues its accurate... right ....is it normal to be at that low of vac??ON IDLE??

25-30 inches of vaccuum in idle is not normal.. should be around 18-22 depending on the condition of your engine.

If I Am 25-30 Vac Does It Mean My Engine Is In Bad Condition????... How Do I Fix That?
