First is it even true that there's a Turbo kit to go on the 4.0? If so, what power and torque increases are there? Better or worse mileage? If Toyota installs it, is it warranted? My 2011 has only has 25k on it so it still feels "fresh " . But I tow a camper so naturally I'm interested in giving it the best performance I can. But I certainly don't want to lose 5mpg either.
Obviously I'm a total noob to this so be gentle lol.
