I have 550cc injectors + p28 + Hondata 200b and my car kept experiencing a 3 psi drop in boost when VTEC engages while getting it dyno tuned. My tuner tightened all my belts but I'm going tomorrow to the mechanic that installed my SC and get it everything double checked. Any other ideas of what might be the cause of this problem? Thanks!
edit: I got about 225whp (SAE) which is kind of low for 9psi
My mods are
AEM CAI
AEM Pulleys
Mugen Header
Greddy Evo Exhaust
MSD Ignition + MSD SS Blaster Coil
ACT Clutch + Fidanza Flywheel
edit 2: My AWESOME (not) dyno graph with boost loss. A/F hovered around 12.5
