So,
I've always had this fucking boost cut when I raise the boost on my car. At 7psi nothing would happen; it would run fine. Anything higher it would always cut once I got into boost. This was very sporadic and intermittent though. Sometimes when it was hotter out it didn't do it. Sometimes when I took out my exhaust baffle it would do it. I could always count on it happening sooner or later though. Today I was checking out my Injector harness since I noticed that if the wires were moved into a certain position it would cut fuel to injector 3. So I took all the tape off and checked all the wires and retaped them. There had been some oil that got into the harness a long time ago so I finally got fed up with it. Then I checked out my MAF and filter since it was connected to a coupler then maf then another hose to the intake tube. For some reason I went into my room and looked at the other three MAF's that came with my car. I grabbed the cleanest looking one with the same plug; KA24DE. It had a black plastic adapter for a filter on it and my air filter was too small to fit over it. I grabbed my heat gun and heated up the rubber on the filter then slipped it on and tightened it down. I replaced it with the old one and tried to start my car. No good. It wouldn't run right. I swapped the black plastic adapter onto my original MAF and had to drill out the holes a bit since it was a little bit bigger (i think this was the cure) and then tightened it down and installed it. Then I went for a drive and noticed the flutter was a little higher pitched when I let off the throttle. I got on the freeway and got into boost. No cut whatsoever. Didn't matter what RPM I started as it usually happened the worst when I went from 5th at 65 to 3rd and slowly crept to full throttle. I did it multiple times and it didn't happen. So I turned the boost up to 13psi and it still didn't happen. I was so fucking stoked since I've been dealing with this since I got it and have researched the fuck out of fuel cut, ignition cut, boost cut and anything in between to no avail. Finally makes me like my car.
