Help can anyone tell me what my autometer sould be reading at idle
I need to know if my autometer guge is reading correctly at idle. At 940-1000 rpm it reads 10psi. Is this ok??? If I lower the RPM to 880 it reads about 5psi-opsi.
I need to know if I'm damaging the engine.

Also what should it be reading on acceleration and on boost??

Any help would be greatly appriciated. Thanks Diego

its basically impossible to make that kinda boost @ idle so im guessing its vaume.. 15kpa is around the norm @ 750rpms usally the higher the idle the lower the vac

with engine warm, holding rpms at 3k you should see 50 psi minimum.
