what u pay for it all and did u notice a difference? did u need a tune?

 

i paid $250 and kept my core for when i sell the truck later. chipping the truck was not required, the stock ECM compensates after about 20 miles or so. a few thousand miles later though i did buy a superchips system. i saw a definite improvement while towing. i haul about 7500 pounds of trailer and dirt bikes when i go out riding, the throttle body helped in the hills. most importantly though since I'm in California its 100% illegal to use an aftermarket throttle body so using a bored one keeps up appearances. even holding them side by side while you can spot differences you couldn't tell what was stock and what wasn't
