Hello and welcome.

Hello and welcome to Briskoda. You'll probably want to post in the car specific forum to get an answer to your question.

:iagree:, choose the relevant forum, and post there, remembering to say which base tune the engine has. Some of them have engine-specific features or problems, that only apply to (or occur in) one specific tune.
