BRZ shuttering/pulling power away while accelerating.
 

Hello. I’m having a issue with my BRZ shaking or stuttering while I’m accelerating. This only happens when the car is warm and I’ve been driving for about 30 mins. Car is not throwing any codes and the car revs fine no shakes or stuttering while I’m in neutral and rev the motor. I’m pretty sure one of the motor mounts is bad or a transmission mount. Probably both. Have the Cusco diff brace and while line diff mounts as well. So I don’t think it’s the diff. Could a bad mount cause it’s to stutter like this? It just doesn’t make sense because it only happens when it’s warm. Could that be the high pressure fuel pump? Again not getting any codes so idk.

I appreciate the help!
