I was thinking on picking one of these up myself. I was told you could go Lexus AFM, 255LPH fuel pump. 550 Injecters and that fuel cut defencer and you can run 15psi all day.

This is was I was told, Not sure how accurate it is. I was wondering myself.

in short: FCD=bad shortcut

Just get a fuel regulator, pump, injectors, and a fuel computer and you will be set for pretty much any set up.

I have all the mods, got the FCD, installed it, and imediately ripped it out as fast as i could. The engine ran like absolute crap with it in and was back to normal once it was out.

A fuel cut defencer will allow you to boost as much as you want (theoretically). If you do not have sufficient fuel going into your engine to compensate for the higher compression from boosting, then detonation is only a few RPM's away .

In short, make sure you have a wideband and enough fuel so you can monitor what's going on with that thing installed.
