Drove my 21 wrx to work today. I was running late so I hopped in and left it was 10 degrees. Started fine but when I got on the main road and got into the throttle it lacked power and ran rough. No engine light no codes nothing. I backed off and drove it easy and it was ok. Basically it did it when it would hit boost I think. Once it warmed up it was fine and happy. Does have a Cobb access port stage 1 93 octane tune. Not sure why it behaved this way. Any thoughts?
