Never had mine loose power under hard acceleration.Lately I have been driving in comp mode because I don't like the feedback when the computer "takes control"( esc,tc). If it spins in comp mode,it spins.No power reduction. Sounds like the OP's car is not recognizing the comp mode input. Have the dealer take a look. This is not normal.
By the way.Mine is also a 2010 without turbo upgrade.

 

Can you try something for me? Put it in comp mode, put the transmission in "I", one foot on the brake, the other on the gas, bring the RPM's to 1500-2000, take your foot off the brake, plant the accelerator and tell me what happens. If yours doesn't spin then cut, and ignore the APP input until everything calms down, I'll bring mine in to the dealer this week.

Yes, I'm serious.

Thanks.

 

I didnt get a chance to BUT, Would this have ANYTHING to do with freezig weather? Temp outside was 29 when this occured. Could the computer be sensing it could be ice and have only usable power to get car moving? Immediatly when I took off gas and replanted, it came back to life, or did 5mph roll and floored, it was also fine... Made me think...

 

Also keep in mind, NO codes or warning lights, just the flash of TC working after breaking tires loose initally

 

I dont have any issues with mine roasting tires. I can sit in one spot doing so and the car wont pull power one bit

 

Was your car fully warmed up?

 

Yes checked that too 190 on the coolant. Strange it runs fine all other times.

 

Plus your in COMP mode....which is used for performance runs...goes counter to the intended results....go to traction off and ECS off mode and see what happens...this turns everything off........hold the TC switch for 10 sec...report back

 

Is yours a 2010?

 

Mine will do the same, regardless of the ECS/TCS mode.
