[QUOTE="LT1BIRD, post: 16822485, member: 152931"] hey bud! its an aftermarket boost gauge... not new.... i had the 4" pulley on before with the 7.25 balancer.. but I just remeasured it and its really a 7.00 inch.. that brings down the boost to like 16.5lb .... on the 4" pulley I was getting 7-8LB so not to far from the 8.7 it should be.. so losing 3 psi from headers and intake.. does anyone have similar loses? i dont think the belt is slipping (6 rib) as i watch the boost and it seems somewhat stable... 12 psi quick.. then goes up to 13 around redline...
