hi everyone! I need help! When I'm at about 3000 rpm's i only make 8-10 psi and then it stutters and pops. any ideas? maybe spark blow out? Thought that would be unlikely since 8 psi is not that much... Another problem is I'm only making 10 psi.... with 20% OD with MPX case and intake plenum????? Bypass valve is working properly and I've done multiple pressure leak checks! nothing. Any ideas?
