I have the diablo predator and was wondering how to stack it with the puck. do i have to download the stackable tunes, if so how do i do that or am i better off just staying with the predator. thxs

 

My predator came with the stacker tunes. Fill out your sig and I'm sure some other guys will jump in. I leave mine on the extreme stacker tune so i have a little adjustability with the puck. Make sure you have gauges though. This puppy will run hot.

 

Diablo predator has stacker tunes and regular tunes built in to the downloader. If you want more power and you have a 03-05 you can get puffer stacker and its great us 05-07 guys are dying for it.

 

Your truck will run better with no puck and the Predator on the non-stack tunes. Mine does anyways......

 

I actually made more power with the puck off (only 3 hp more, but...). The puck just made the power come on earlier.

 

Thats what i have been told too have played with the puck much not a huge fan but for the price and someone wanting some fuel mileage cant beat it.

 

I couldnt tell much of a difference with the puck on or off... it just feels like the power comes on a little quicker

 

Just how much increase in mpg do most people get with the puck?
Thanks!

 

If you flip on the puck during acceleration you can definitely feel it. I leave mine off most of the time and just use the non stacker tunes. While towing I use the regular tow tune, and flip the switch when I need a bit more oomph. Other than that it stays off.

 

have seen increases from mid 14s to low 18s.

 

I saw no mpg increase with either the Puck or the Predator...

 

i gained aprox 150 km range to a tank of fuel when running the predator on performance non stack tune, i think hand calc it worked out to abour 2 mpg increase

 

thxs for the info i guess i will keep the predator. i have a 07 5.9. when i have time i will make my sig.

 

No increase here with the Puck alone.

 

What do ya' mean Creed? I ordered the stack, and have yet to open the box with the puck. I wonder if it smokes more with the puck. What are these ''puffer tunes''? I have seen it mentioned but don't really know what it is.

Thanx.
