i have never got great milage gains using a juice on a 3rd gen and my thinking on that is because it changes duration, timing, and map and on these trucks the best milage gains come from chaning the rail pressure and timing. that said most pressure boxes only change the rail pressure and map but not timing (ts mp8, edge ez, dr performance) and that is why they are stackable with the duration boxs or tuners. the only ways to change both rail pressure and timing with a single unit right now is to use a smarty SR, a TST CR, or EFI Live. of these EFI Live is the only one that allows the user to turn off the post injection event which the 610 series engines have and that is showing decent gains and the very minimal upper rpm power loss can easily be adjusted with the duration tables, both of my CR trucks i have tuned with EFI Live and i have used all of the above mentioned products. EFI Live has given me the most milage gain followed second by using a smarty SR with a low duration tune and mostly using the rail pressure and the higher timing settings
