My poor poopra is having some issues. I just rebuilt the top end recently with stage 2 cams, springs, valves, valve guides etc, it has a 60 trim ct26 with supporting mods such as 550cc injectors, walbro and im tuning it with a afc neo. Currently the boost controller is set at 15psi. I've put around 1200 miles on the new top end with absolutely no issues untill recently.
So the issue happens whenever im close to full boost. Under a decent amount of load. It spools and runs fine but once i get close to that 15psi it cuts out pretty violently. Almost like fuel cut but i've never had this happen till recently. A big hiccup then once im off the throttle everythings fine. What could this be from? I checked all the plumbing and i dont have any vac leaks etcetc.
I really hope i laid out enough information i'm trying to do some research right now so id appreciate any insight to get this problem fixed.
