BigSur - I didn't notice any "spreading", as you put it, but you DO have to push the right side down so that the pod "snaps" on. This actually holds it in place very securely, which I see as a good thing.

Regarding using the custom options menu - I've spent a lot of time with this thing. I do not see any problem using it to set your TS and GR immediately after completing the first programming session without it. However, I'd be much more cautious about changing other parameters, especially if you have custom tunes. For this, I strongly recommend driving the truck "as is" for a while to figure out what it is that you need to change (if anything at all). Then, make sure you understand what it is you're changing!

To minimize confusing interactions, try to work with one thing at a time and TEST. And, resist the tendency to make big changes.

Remember, your tunes were written by a "pro". If you modify them, you ought to have a pretty good reason. I get very impatient with people who want to know, "How to make Bill's tunes better".

And, please don't hear me making any accusing statements toward you here. I just feel it's good to bring these points up again since the subject comes up so often. I suspect you've done it, but if not, please read through the Q&A on Custom Options to get a better idea of what's going on.
