i took my plate out today and truly belive that it would have made more power with a good cut plate, when i drive it it feels strong then feels like it defuels hard. so i came home and ground me a plate similar to a 10, i have yet to try it but am 100% sure that a good plate would run stronger.
on my completly stock truck and no plate it dynoed 225/650
just some info to chew on, take it how you will.
