So, I dont know if it is the power from the new 14X3 or the power from what the dealership did, but my truck had a surprising power boost, it is quick! I love the throttle response it has, and the power band is great for a 5.2 ltr v8 in a 4wd half ton truck, it reaches about 2.5 grand rpms and really jumps! It hasnt been this powerful as long as I have owned it, I dont remember it ever being this powerful, not even when it was bought brand new.
