EDIT

I would just like to get it running without a misfire right now. It was rough, I've smoothened it out but still have a little ways to go.

get a nice spool on it and hear it wind down a track smoking tires and other cars in a nice class.

Hey there man you got a pretty sweet ride there to answer your question about misfires the main things would be check the harness for the coil pack module, check the coil module and the coils, in some cases like mine I had to run a degree or 2 colder spark plugs, I am no expert but I have worked on enough of these cars to know what works get yourself a good scanner check check double check that kr you will hear everyone say that it's true you can't run clean boost on kr and look for boost leaks
