Welcome Jtone, glad to have you in the group man.. If you need any help, I'm in Fort Myers just hit me up.. There's a few of us in the group chat and also on here who've been through just about every N54 nightmare you could imagine.. I do all my own work too, don't really trust many shops around here.. Plus there's really not much you can't do on your own with this motor.. It's tight work space in there, but definitely manageable..

Don't waste your money on a chargepipe unless you need to. I ran 18.5 psi for a year and sold the car still holding boost strong on stock DVs. Don't change it unless they leak.

And it may sound kind of simple, but one thing I'd start with is plugs, coils, and injectors.. Mine did exactly as you described and it was a fried MOSFET chip inside my DME, and also one of my coils was fried.. The MOSFET in the DME was a cheap easy fix at a local TV Repair shop, and the coils I got for the low on ebay.. I'd definitely start with the plugs and coils and see if that fixes it.. Also, what are you using to read codes..??

I have a 2007 with 125,000 miles on it. If you have E85 available in your area you will have a pretty hot runner pretty quick.
I replaced my spark plugs, Installed a VRSF 5" stepped intercooler, bought the metal charge pipe with the FMIC, Got the 3" catless down pipes from vrsf, dropped in a upgr8 air filter. Bought MHD programmer, monitor and some tunes. WedgePerformance hooked me up with a custom tune installed via MHD. It's an E50 tune, 21 psi boost target. Stock turbos won't go much past 400 whp but with a good tune you will get over 500 ft/lbs of torque. Torque is what moves the vehicle. Anyway here are some of my runs short shifting at around 5000 rpm. It's enough power that with 265/35-18's AA traction rating all season radials can barely hold the power in 3rd gear. I have boost reduced to 13 in 1st and 17 in 2nd and it still spins the tires. Some Virtual dyno runs to look at.
