I dont believe so but your running an 04' and I know that those were coming out of the factory already running in near lean condition so adding a CAI on top of that without custom tunes would not be good. But if you get a Gryphon with custom tunes they will tune your engine to get the maximum performance out of the CAI without harm to your engine.

Did the CAI cause your truck to run lean? or did the edge take care of that?

I put in a Volant CAI at the same time and noticed a huge differance in power gain, it feels better than stock with stock tires in the 93 performance mode and went up about 2 mpg's in this mode. At first I ran the 87 tranny and noticed a huge differance as well I finally feel like I can step on it again and pass someone. All in all I put it back to stock for a little bit just to get mpg readings off it and was running a 11mpg average now when im getting anywheres between 13-15mpg but idk how much the Volant is playing into this also. Cant wait for my custom tunes to be ready now and see what the differance is.

Hey man nice truck! how much did that gryphon help out with your tires even with the canned tunes (power and mpg)? Just curious as to what i can look forward to while waiting for my custom tunes.
