I just bought a Taisco Boost Gauge, got it cheap off Ebay, I know I am about to get "you get what you pay for" but I am interested to know how accurate they are. when I put it on it says my car is running 9-10 lb boost when the boost cotroller is turned right down, it should read 7lb which is stock boost My origanal boost Gauge was showing 7lb, so are asking this question how acurate are they????. When i was driving in second at 4000rpm constant then put the boot in, it shot up to 11-12 & shat myself waiting for the fins to shoot out the zorst I backed of asap. Do boost controllers raise your boost from standard. please help not game to turn bleed valve up.
