I thought it was the over/under spark, but I don't think that's the problem?

"Stage 2" could mean anything. Company's put that name with their products for some reason.

Manufacturer name and a part number would help tremendously.

Hi Gary,

Give this a go. There were a few things off in the tune that I've tidied up. The main thing was that your base running airflow final minimum was jacked way up. Log dynamic airflow in both park and in gear and take note of the values to populate the table. Its always helpful to post a log with your post as well.

Thanks for your help. v/r, Gary
