I have a BULLY DOG POWER PUP in my 6.4...barely any noticable difference (a bit more power and matbe .5 mpg if I'm lucky). I got this because I had heard good things about BD. I guess I jumped the gun...
I wonder if BD is going to compete with the other guys as far as their DBF deletes or not. Anyone know any thing.
As of now, I pulled it out to take it in for a new a/c system/radiator/oil pump seals/tail gate...
Nice truck, but expensive rentals...
