AWD turbos aren't much different than the stock MHI units. The car will run and drive just fine without a tune. The only this is you may experience some overboost induced throttle closures but at the stock boost level you probably won't even feel them.
With the catless DPs you will throw a CEL without a tune or DPfix.

However, that's a long list of parts(and a lot of money) to waste because the car isn't tuned to take advantage of them. The right thing to do would be to fix the misfire issue and then install the bolt-ons.
