Ok, to abbreviate the story:

2003 turbo motor swap into GTUs, with 3" turbo back + AVCR - boosts to .6 bar fine except hits fuel cut past that

2004 haltech e6k install - wierd pinging problem under any manifold pressure, finally solved this last week(combination of plugs being too hot and ignition wired backwards)

So now that the car is actually safe to boost, I've been boosting it everywhere, but it hits a wall at .45 bar. No real loss of power, no stuttering, just won't rev past .45 bar(got it to .48 at the top of 3rd gear once). What gives? I just reseated the uim too with a fresh gasket, gasket sealer, and checked all vac. hoses to make sure they're not leaking. Adjusting the AVCR's boost levels doesn't affect my max boost. Any ideas?

P.S. .45 bar = 6.5psi
P.P.S. It's also been lumpily idling a little low(700rpms) ever since I pulled the uim off to check and see if my secondaries were bad(see aforementioned pinging problem), although this may be due to the different map I'm running now.
