I just went to a 147.5 from a 145 main. With a hmf series 1and a uni stage 2 air filter. 1.5 turns out on the af screw. The issue im having is it seems to idle fine, then rev up, then idle fine. No bogging out or wot or midrange issues. No air leaks, timings on, and fresh 93 octane that's fresh. Any ideas
