well the engine is not bored over or anything like that. but this is just a basic on the road around town/mudding truck. the noise does get complaints from the neighbours a lil ways down the road lol. but to hit the 6000 band thats when i stomp and the tires begin to roast then it will rev like mad. when i got good traction it will start losing on acceleration after 5500. i will post pics when i get the chance
