I can't find where/if you specified in that thread, was that with the stock MAXX 171 version or the Shocker 185 CNC version? The ProMAXX site says the 171 will do [email protected]" on the intake and the 185 CNC is at [email protected]". Your result on your bench was in the middle, [email protected]".
