Cold start in the morning and the exhaust brake on and high idle.

Starts dumping out the exhaust and engine has a flutter to it.

If exhaust brake is shut off it quits doing it.

I contacted RaceME Eu just waiting on a response from them.

I am in basic tuning and it is updated to the newest software.

Anyone have any ideas off the top of there head still very new to all of this?

Thank you!
