After you load a tune, you need to give the trans time/miles for it to relearn.
If normal driving don't help with smoother shifts, you can read post #13 and give it a try.
You can play with the settings, I would suggest to only go in 5% increments at a time, trial and error. Here is a run down of what the settings do.
Custom tunes make a big difference, canned tunes suck!!! When you contact a custom tune writer, they will need you truck mods, strategy,SCT device serial number, and credit card number. Explain to them what you are looking for in a tune. The tunes will be sent to you in your email as an attachment. Make sure your PC is set up with the SCT software (Device updater,firmware, and tune revision). Return your truck back to stock before you update your SCT device.
