Custom Tune Usability Question and Major Props

[Jackpine]

The "performance tune" you got, judging from your earlier remarks, is possibly geared more towards fuel economy and highway cruising.

You're going to feel more "oomph" right away in the tow tune since it's set up to get your truck and the load it's pulling, moving away from a standstill. That's where the tow tune has to do its work. Once the whole mess is up to speed, the additional power requirement is reduced.
