Message	Check fuel pressure if you don't have wideband o2. It's probably from lack of air or ignition, but check the fuel first unless you're positive it's not running lean. You don't want to risk engine damage. Run ecu codes. Then, do a leak test. Be aware that pcv valves/hoses can leak under higher pressures that only shows up when under heavy boosting (from what I've seen). Then try putting back recircs or other blowoff valves. Then swap cas. Then swap ptu. If that doesn't get it, I'll be amazed. Keep us updated.
