    VE coefficients under speed density changing when tuning VVE?

    Hi all, I was comparing my original tune to that of my attempt to tune the VVE table. I found under engine\airflow\speed density the VE Coefficients have changed after I changed my VVE table. This all makes sense since I hit the "calculate coefficients" button during this process. But I wanted to check. Should I do anything with those charts or leave them just as HP tuners changed them? They seem adjustable? I only found them during my compare and have left them just as they are calculated based on my new table.
    Thanks

    Thanks for that reassurance. that made sense to me but there are so many tabs, fields and charts to change I just wanted to confirm.
