Well said Jack.
I am not trying to diss the tuning companies, but you have to remember that they are in the business to earn money and do not always have the budget to test things to the extreme. (and sometimes they just plain bullsh*t). Read what the tuning companies say, but do not believe everything blindly.
I am a firm believer in the Latin phrase "Caveat Emptor" (let the buyer beware).
