Default My 4L80 tune sucks

I've been trying to get a few bugs out of my tranny tune lately. It shifts funny like jumping back and forth between gears during hard acceleration.

When it's time to shift into 4th, it'll go into 4th for a split second and then back to 3rd for a split second, then back to 4th. It's irritating, hard on the trans and costing me time.

I'm hoping someone could look at my tune and see what might be causing this, or maybe provide a solid tune that I could steal some tables out of.

What tuning software are you using? Post up your tune.

Not sure how to post my tune on the forum but I have one person looking at it via email. I'm using HPTuners.
