Has anyone else experienced better performance when the air is cold? Took mine out for first time in 3 weeks and it was absolutely flying. Have also found it's a bit sluggish when the air is really hot (well OK that is with 2 tons of horse and trailer on the back!)

Of course, especially so with turbo charged motors. At this time of year in the cold the air becomes denser, cooler intake temps equal a bigger bang! Your intercooler will become much more efficient also so it's a double win
