Hesitation in boost

[Slow99x]

I am currently experiencing a P304 code from the ECU and the car seems to hesitate when at full throttle. I've tried to remmedy this by adding an electronic boost controller(Greddy Profec-B), Walbro 255 fuel pump, NGK-R spark plugs, MSD 8.5 mm wires, Apexi S-AFC, and it seems to go away with each one that I add but then comes back. I even turned the boost back down to 12 psi to try to find the problem and I'm at a loss. The next step that I can think of would be putting a new coil and an MSD ignition box. I talked to the Mitsubishi dealer and they say it could be a knock sensor. If anyone has experienced this problem and finally solved it I would really like to know what you did to fix the situation. Thanks!

Check you injectors. Probably clogged

I already found what the problem was. One of the MSD wires got condesation into it and the spark arched right through the side of the boot and was hitting the block. I replaced the wire and it runs perfectly.
