I have read some speculations about supposed mpg gains and/or losses. Now my question, has anybody experimented with this idea that can confirm or discredit the mpg change theory?

At someone else's request, I actually did this and tested this with someone about 2 years ago on ISX with holset turbo. Fuel mileage actually dropped off a tiny bit and it made no significant increase in sound. -- It is a crock of total baloney red-neck pick-up truck butcher bulls$it if you ask me!.
