I've looked at some of the testimonials and been to the web site. But before I drop $75 on something that could at best solve the sticky injectors on cold starts or at worse screw up a $14,000 engine, what say the sages of SuperDutyDiesel.com? Is this product any good? Bad? Alternate suggestions? The sticky injectors are a nuisance and certainly aren't doing the engine any good. But it seems to be a common problem, common enough to have made someone come up with a solution. Your input is appreciated. Like Bartles and Jaymes used to say "Thank you for your support!"
