Power shifting?

Anyone have success with this? For a manual boosted car this would be ideal. But I don't know if the trans in these cars can handle that. Anyone try this and what were your results?

NOT worth the driveline shock you're going to create. Is it faster? Possibly. Will it give you a quicker time? Possibly. Will it break your transmission sooner? Possibly.
Why take the chance? In the end it won't be worth it.

Yeah, I used to do it in my Camaro, but I had a built drivetrain. Made a decent difference. I would think it would be a significant difference in these cars due to the ability to hold boost on shifts. I def notice lag or some sort of delay on fast shifts. I was hoping to eliminate this.

Are you running a JB tune? Many people got rid of their JB tune cause of the bog on fast shifts.

No, Procede V4 autotune.
