I got an 05 SD and just put the green intake on and a supposed to be new xzt2 (part# f6lxzt2) and gained an extra 3mpg but im thinking with just the intake.. I didn't feel no extra hp.. which i guess 65 isn't a whole lot lol, but at 70 when i punch it it revs up and just lugs the crap out of it and doesn't go anywhere and i let off and the ol turbo barks pretty bad.. Anybody know what this could be??
