I thought their tune was a bit more on the conservative side unless all of your bolt-ons were from MAP? I'd like to see a dyno comparison of the stock tune vs their custom tune for a stock car.
Here's a thread I started about colder plugs. It has info on what plugs can be used, what the benefits of colder plugs are, etc.
Stock gap is 0.0295. No, switching to a colder plug on a stock tune with a catback will not make a difference. Everyone hears about running a colder plug and thinks if they just put a 1 step colder plug in, their car will be faster. Trust that Ford did a lot of engineering to determine the best range for the plug to operate. Ford Performance even stuck with the stock plugs and gap for their performance tune for the ecoboost. Putting colder plugs in will just have them operating at too low a temp and they foul easy. With a pro tune, yes, they push the operating limits and benefit from a colder plug. Some of them also push more boost so reducing the gap helps prevent spark blow out. You wan to run the largest gap you can without getting spark blow out to ensure the complete and even burn of the fuel in the combustion chamber. I have the stock plugs gapped at .029 and they're working great! I pull them and inspect them every 5k miles during oil changes.
I believe Adam says to torque to 10lbs on his website.
Missed that detail on his site! It's been running fine with 18lbs, so hopefully it's fine.
I'm sorry I don't think he is right 12lb is manufactory spec..:ford:
