I never had good luck with the bully dog tunes on my 04.5. 2.4.1 on performance ran ok but i switched to a smarty and its totallly night and day more power and smoother. thats just my truck though so it may not always be the case

PA...what exactly do you mean by "good luck"? Thanks!

they didnt run well at all on my 04.5. I had a lift pump and plently of rail pressure (24,000+) and it just smoked and was a total dog. hot too. switched to a smarty and it works awesome. Larrys do run awesome on the 06's tho, prob stouter than the smarty
