Default Techs can't figure out my P0336 and all misfire

13 WRX grimmspeed downpipe and aos on Cobb stage 2 stock intake map.
While pulling around 90+ got a all four misfire code alone with crank sensor code and started bucking here and there.
Car still starts but revs high when first started and wants to bog and stall out when returning to idle. No DAM drops or feedback knock.
I replaced the crank sensor under the alternator with no improvement.
Non Subaru tech said timing looks good but it is running rich and wants to put Cobb back to factory map tomorrow. Also wants to put non AutoZone crank sensor in. Short block was done by them about 12k ago with no problems. Problem I am having is the two Subaru tuner techs don't work there anymore. Any ideas what's going on?
