Pretty new to the turbo world. Only mod is the Berk downpipe on otherwise bone stock 3rd gen engine, running 12psi according to my gauge. Runs, idles and goes just fine.....just smells rich to me, exhaust tip is a little on the dark side too. Is it normal behavior or what? where do I start my troubleshooting?

These cars run on the rich side stock for sure. Mine usually smells fine at idle, inside of my exhaust is usually black. It runs really rich on boost though
Also, keep in mind that there is no secondary cat on these cars, so a swapped DP means no catalytic converter = smells terrible. If you want to be on the safe side, like others have said, use a wideband to check AFRs......if you know someone who tunes they probably have a sniffer you could clip to the exhaust outlet. I personally wouldn't worry about it though.....they are supposed to run rich stock. Boost should be ~13psi in all gears except 1st (maybe 2nd as well....been a while since I've driven the GT4). For the boost gauge, tee off of the blocked off port on the bottom and middle of the IM. DO NOT use the line the MAP sensor is reading from.
