I wouldn't normally do this, but I came across a very interesting homepage for a business alot of 6.0L guys turn to. Gearhead Automotive Performance.
Gearhead Automotive Performance
Matt, right on his front page, has taken a stand against "smoke" files, for lack of a better term. Even to the point where he states he will turn business away for those that ask for such a file. He takes a stand against street racing, and calls out smokeing the streets for the current emissions regulations. I take it that Matt wants to be part of the solution, and maintain our freedom to modify our trucks to get the most out of them.
Matt, for your efforts to tuning for power, vise smoke. I salute you.
(Not sure if Matt is even a member of this site, and this thread is not intended to promote his business, in and of itself. But I wanted to recognize the effort, and the resigned page of the website, and thank Matt for taking this stand. I grow tired of watching the smoke videos, watching the how-to-smoke-threads turn south, and the regulation that may just kill this hobby of ours.)
