: Predator noisy at 65hp Tune

Installed the Predator a couple of weeks ago on my LLY and I must admit, it's simple to use and provides plenty of power. Running to 40 hp tune, it's quite peppy from the line and provides alot of giddy-up thru all gears w/o Allison issues, but at 65hp, the clatter is annoying and was wondering if this would go away after time. Maybe the advance timing of the software in the Predator or is this the norm.

No it won't go away with time. If you truck hasn't been reflashed with the latest calibration that might make it a bit more queit. Don't forget to remove your Predator programming before getting it reflashed ;)

It was reflashed before the Predator tune install and it was quicker and quieter afterwards. The 40hp is like stock but as I said, the 65 is noisy. Have you any experience w/ the 100?

Max Power, just the question I wanted to know. Will it void a warrenty?

It definately can depending on your dealer. Some seem to have a REAL problem with chips/programmers. It is always a good idea to remove any upgrades before taking it to the dealer.
