i Have a b16b with a milled gsr head, ported tb,sk2 pro intake manifold, aem intake, 4-1 headers, 2 1/4, exaust, running on a itr program

what kind of milage sould i be getting??? on a full 9 gallon tank in my cx EG i only get about 160-180 running on a itr program in my p28

does this sound about right ?

i tried an old gsr mild program and i get to almost 300 to the tank...

what is the stock fuel pressure on a b16b ? my helms manuel says 52 for an ITR...
would that be the same for a B16b?

thanks for any input
