Detonation Problem
I just installed a IHI turbo setup for my 98 civic(D16y7). With the wastegate on my car it runs 4psi, feels like stock for me, so i unpluged the wastegate and the car runs a solid 7psi it never goes beyond that point and hawls some ***, but at high rpm(4k and beyond) the detonation begins. I run 93 octane and just put in a new fuel filter,and spark plugs. I cant figure out whats he problem, is the car lacking fuel? if so should i just add a fuel pressure regulator or a fuel pressure regulator with new injectors? thanks for any advice.

You are boosting without fuel management?

Re:Detonation Problem
What size FMU are you using? If it is at least a 10:1 you should have way more than enough fuel. Does it fall on its face and put you through the windshield(not really, but..)? I doubt a pump would fix that problem. Do you have any gauges at all?
