[quote="Herculou"]Are you talking just the puck or the programer? The Predator programer will give you mild to extream, even on the 60hp setting you will noitce a BIG differance. If you get on it it will smoke a lot more though.
I usually run the 100hp setting ...

Can anyone please explain the differences in the two modules?

I'm new at modding diesels.

What I'm looking for is a mild, but noticiable increase in power and mpg's, but do not want warranty issues on a new truck.

I have a 4" mbrp, and will add a stage II air intake and guages shortly after or ...

Nice...thanks for getting back so quick.

Now I want one bad!

I know it can revert back to stock settings, but will the dealer be able to tell if the program was ever modified? Concerned about warranty issues...

I'm more interested in economy and drivetrain safety - can I safely run the econo mode without modding the exhaust and air flo?

For speed, I have 2 sportbikes!
