When I am in 5th gear, when I go WOT, all the sudden it feels like fuel cut. The ASC off light turns on and the service light pops up. The engine does not respond to any gas pedal input and I have to brake to a complete stop. Then the engine idles horribly at 2000 rpm. I shut off the car for 5 seconds, restart it, and then the ASC light goes away. Anyone else have this issue or have any input? Thanks!

 

ASC off light has come on for me as well. But I am still able to drive the car fine. Anyone know what the issue is?

 

You guys are likely hitting boost cut or a limp mode. Verify you aren't exceeding the boost limits load percent values and look into using the DTC disable codes to avoid setting off airflow and torque limit table limp modes.

 

+1. Have whoever tuned your cars check that. If you don't have a tune GET ONE!
