A tune would have to be so far off to lose 1.2 seconds on a quarter mile it's not even funny. Are you sure there isn't another cause?

Also, the cost of tuning software is WELL worth it when you take into account bs situations like this and others.

The tune is the only thing that has been changed since the 16.0. Have you ever drove your truck when its cold before it warms up and it seems like it makes a lot more noise from under the hood? Like the intake is sucking in major amounts of air? Because after the dynotune thats how it drives and i can't figure out what is doing it
