You can guarantee Ford didn't miss the tune these guys discovered in their garage. The big three diesel truck manufactor's could tune these trucks to produce much more power than we see today. Trying to meet emissions would never happen if they turned them up.
Remarkable ignorance. The first thing guys do who plan to tune for power is strip off the emissions equipment as they could care less about the air the rest of us and children have to breathe. Second thing they do is spend $3000 or more to have the transmission "built" so it can take the stress of the added horsepower. And these transmissions are not used in towing situations and are still vulnerable.
Easy to boost horsepower when you don't have to cover the warranty when parts start to break in the engine, transmission and the drivetrain components. If the engine runs hotter while no worries one can spend the money on a upgrade of the engine cooler. Need more fuel to keep the injectors lubricated, no problem simply buy a new external filter setup and add a lift pump. Always easier to spend other people's money.
None of the tuner companies will provide a figure for the improved fuel economy their very expensive products will provide. The magazines that want the advertising revenue from these companies will periodically to a review/test and the best gain I have seen is 1/2 MPG and the test was too short, involved no towing, nor driving in mountainous terrain or even stop and go city driving. Even then one would have to drive 100,000 miles to breakeven on the cost of the tuner, ignoring all the not so well hidden costs with these modifications.
I agree 100% with the statements regarding the idiocy that some programmer in a garage someplace has found a miracle cure for improving MPG for all the hundreds of truck models and model years that provide better fuel economy than the thousands of engineers working for the truck manufacturers have somehow missed for decades.
GM, Ram, and Ford, would kill without hesitation to get technology that would give them an edge over the competition. At the very least they could have bought all of these tuner guys for less money than they spend for fuel for their corporate jets. These companies have done this many times in the past and the only reason they are not doing it with the tuner guys is that the stuff is bogus.
