Default 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 need some kind of extra fuel.... FMU maybe

your engine won't last long if you keep beating it to death without adding extra fuel

what do you mean. it'll be hard to make it run right if you get bigger injectors and try and adjust the fuel pressure around. the easiest way is stock injectors and FMU

I would look into an upgraded fuel pump if your running an FMU also.

You are boosting without fuel management?

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?
