alright so ive got a 94 ls boosted on 7psi. I replaced the intake manifold gasket with a thicker nitrile/rubber gasket from mr. gasket and adjusted my idle back to around 850-900 from the 1100 it was set at, and now im back firing when i shift through gears, but only when the bov does blow off or flutter, or when i coast in gear, any ideas?

yea its chipped on chrome and its tuned for my set up...it never did it before, only started after installing the im gasket and readjusting the idle screw
