Ok Im currently running about 18psi. My car has recently began bucking/backfiring at around 5000rpm in hard acceleration. And will not rev any higher. Does this sound like a spark issue to you? Ne help would be nice.

Bucking/backfiring=yes sounds like a spark issue, check your plug condition and gap.

Feels like you hit a brick wall=fuel cut.

You need to be running NGK BPR6ES (BPR7ES with fuel mods). Gapped at .028".
Nothing else will work.

try turning the boost down a bit and see what happens first.

Is your mods list up to date? Have you checked for boost leaks?

What's a "ne"?

Well I finally found the problem with my Dsm. About 3 days ago my car took about 15 seconds to start. I knew that it was fuel. After running for about 30 minutes all the way to work I could watch my gas gauge fall. So what the problem was, was that my fuel line at the sender was leaking all kinds of fuel and at work i put the fuel pressure gauge on and it read 25 haha not suppose to happen. Well thanks for all the help and to ne one else who might have problems.
