2G newbie questions!

[XiKeiyaZI]

So I have myself a 2G now, and I'm not too familiar with it, so I'd like to ask a few questions and see what I can get out of it.

My mods are listed in my profile. So don't ask " what's done to it "

1 : It seems to be running a tad Lean.
2 : When accelerating under boost, it misses.
3 : It has a SOMEWHAT rough idle.

I pulled the plugs and they are all burning just a little lean. Not bad or damaging, but just enough to burn on the hot side. Infact, it was hot enough to warp the boot on #2 plug wire. The engine itself doesn't run hot, however. 2 Hours of driving and never above the mid-mark.

Any thoughts? Again, check profile for mods.

Just confirmed (compression test) - 160 Across the Board.

So, update :

Been driving the car a few days now. It's still missing/backfiring lightly under decel. Not sure what the issue is there other than a major Boost Leak somewhere.

When I hit 13ish PSI, it fuel-cuts. I was informed that the FP in the car is the Wally 255. Would that effect this? =/

I just took it out to check the whole fuel cut thing... got up beside my friend in his S14 240, we both took off so he could watch how the car was acting. In second gear around 5K the car started sputtering. I shifted to third, WOT, at about 4K, the car felt like it hit a wall, bucked, backfired, and smoke went everywhere from behind me.

We pulled over, checked everything. Clean Oil. No messes in the engine bay... all was good.

So.. fuel cut? I know that the fuel filter is OOOLLLD... I'm replacing it tomorrow.. but would that being old/dirty cause fuel cut? The car sometimes feels like it's starving for fuel..=/ So of course the Fuel Filter will be changed tomorrow. If that's not the issue, what could it be?

Went and had the codes ran.

1 Code was for the EGR Solenoid?
1 Code was for the Purge Control Solenoid.

How do you properly eliminate these in a 2G? I know in my 1G GSX it was as simple as unplugging them. But I don't want to suffer the CEL and it seems like it's effected the car's power. He cleared the codes and they haven't come back just yet...but yeah, I assume they will. Car is running a bit different.

Any input would be nice.
