I'd take all opinions with a grain of salt especially from folks who are selling/promoting a product.

Do you actually have any experience with the xhp tunes? Which tune are you using. Blow away in what way? Any objective measurement?

The xhp, stage 1,2,3 tunes which I've owned emade a minor difference in cold weather behavior, and a little less clutch slip from a slow roll. But beyond having the gear indicator on the display wasn't even noticeable to anyone who drove the car. I'd lend it to folks and they never noticed a difference per/post tune. ITs not nothing but not major in the list of upgrades.

I'd recommend a trans tune only when you've done all the better bang for a buck things like, engine tune, deletes and etc. If you want that last little bit. But its not going to make a major difference, unless your heavily modded and the upped torque limits maybe of benifit. On a stock car there are better ways to spend money.
