Hi

Is it normal that my 2.9 non crusher put down 19-19.5psi with arh 1 3 /4 header , 3"x pipe to borla stinger ??

My 2.9 non crusher with BBK long tubes, off road x and 2 lb lower makes 20.5 psi. If you have stock lower and 3.5 up top it sounds about right.

Mine put down the same psi with similar exhaust setup, 70* weather, and the 3.5" pulley.

About right. My 2.9 crusher made 20 PSI with a stock lower and the stock 3.5" upper. Stock manifolds, bassani X, borla stingers.

Curious what elevation you are at?

Mine made 15psi with the 3.75 at sea level. Move to 4k elevation and was seeing @12-13. Dropped down to 3.5 and maybe seeing 15 max again.
