I would get a tune ASAP. Until then stay off the turbo. You are pulling timing, you ECU does this to prevent damage to your engine. This also means you are not getting any benefit from your mods.
There are several great tuners over in Maryland.
One other option is an OTS/remote tuned map flashed with a Tactrix or an AP. I don't know what your current situation is as far as that goes.
I will say that Braden at XPT can clean this up for you. If you intend to go with a remote tune Braden is AWESOME to work with. He also works for COBB so if you were not feeling comfortable with that option, that should help.
Research Xtream Performance Tuning and you will find him. Send him a PM with a log and see what he thinks.
