I would check out Profit Labs. They are local and their focus is on actually building and publishing the SEO assets, then tracking what went live. I liked that the reporting included the live URLs instead of just saying work was completed.

Bully Dog is fine for a basic setup, but if you've got any mods or want more control over the tune, 5 Star is the way. They actually dial in the tune based on your specific truck and mods, not just a generic file. My mileage even improved a bit after their tow tune. Worth the extra couple bucks.

Wait, your wall actually started leaning bad just from skipping the line check?

Question if the difference is all that major. Batts are easier to install in most attics anyway. The thermal camera probably makes it look worse than it is.
