Everybody's probably seen the methonal/water injection intercooler kits for sale on the net. I don't think I've seen too many (if any) guys on this thread listing it as a mod. What's the story with it? The description sounds too good to be true.... more power, lower intake temps, lower egt's.

Who has it on their truck? Is it worth it?

Check it out at Heath Diesel - he runs them exclusively, been selling his 6.5LTD version since ca'98.
