I own my own business in custom tuning these things, with simple bolt ons (exhaust, and lift pump) they can push 500+ RWHP. What doesnt help them is they weigh upwards of 7000 lbs. That however means very good traction off the line which accounts for the low (relatively) 1/4 times. These same trucks also get 20+ mpg on the highway.
