boost problem Options

[blckcelica95]

So i began a thread over in Engine/Transmission/Maintenance . but the focus has switched over to more of a forced induction Question. So here whats is going on, last saturday night i took the car out for a ride. eventualy i decided to open her up and i did but soon there after the car started haveing issues boosting.
the best way to described whats going on is that when i get on it at about 3000, give or take a few rpm's ,it begins to just bog down and back fire. i believe its misfiring. it only happens when the car hits around 8 pounds of boost. odd thing is that my a/f is staying around were it used to . 13-11 range. the spark plugs are gapped to the correct gap .30 . my head gasket is good 205 - 210psi accross the board. it has new plugs and wires . the cap and rotor look good. i tried going back to an older fuel map to see if the problem would go away and it stayed. i should also note that the issue happens 90 percent of the time but not always.
i am running out of ideas and could use some help.

ps here the other thread i started

ouch.

i dont like to post in these types of threads, unless im pretty sure what it is.
art is right, 17psi with a ct-26 is not really much use on a 5s, hell, much over 15-16psi even on a 3s is kinda pointless.
bosch wires...BIG no no, especially since your turboed.

new OEM wires, cap and rotor, once a year. at least.

if your needing to run 17psi on a ct26 to make the car fast enough...i would say its time for an upgrade, especially if you have forged internals.

:edit:
i just read your profile.
it says 50 trim to4 compressor in a ct-26.
all that compressor, with no exhaust side work, is pretty much usless, especially on the 5s, we need more flow.
you'll be making a few more hp than a normal 26, with ALOT more exhaust manifold pressure. (more heat) yes, the WI will help with that, but you'd be much better served with a bit larger exhaust housing.
since its a "project car" sounds to me like its time for a larger turbo!
hehhehe
