under boost car hesitates at vtec switch

anybody else have this feeling. One thing my vtec is at 4500 cause im running a p72. and right when the car switches cams the car kinda hesitates. Is there too much timing. the engine is 8.7 to 1 and im running 6 lbs. of boost. My timing is at 16. stock.

any ideas. oh yeah the shitty fmu is my fuel management for now.

VTEC may be kicking in too early. Mine is set at 5500 and it’s a pretty smooth transition. Anything lower than 5000 mine hesitates, as well.

retard timing a bit & see if that helps.

I had the same problem bumped my vtec actavation to 5200 and my hesatation was gone
