I weighed my boat and truck the last time I took it out and it weighed in at 11500 with nobody in it and a full tank of gas. Pulling it with the SC on there is a beautiful thing for sure. It always pulled it fine IMO without it, but it pulls it like a dream now. As far as durability and drive-ability, no complaints so far. With the factory tires my mileage was the same, cept under boost of course. Going up hills on cruise out of OD it purrs with a pound or two of boost...very nice.

If your interested in more towing "grunt", go after torque. A lot of us get hung up with HP readings. Here's an excerpt from an article on the Car Craft web page:
"Engines don't make horsepower; they convert fuel into torque. Torque is the twisting force imparted to the crank flange and then transmitted to the transmission and the rest of the drivetrain. To some degree torque is the grunt that gets things moving, and horsepower is the force that keeps things moving."
"Torque is the static measurement of how much work an engine does, while power is a measure of how fast the work is being done. Since horsepower is calculated from torque, what we are all seeking is the greatest-possible torque value over the broadest-possible rpm range. Horsepower will follow suit, and it will fall in the engine speed range dictated by the many factors that affect the torque curve. The key is selecting the combination of components that will stretch and fatten the torque curve (improve efficiency) as much as possible in the driving range we prefer."
"In the 18th century, steam engine inventor James Watt sought a way to equate the work his steam engine could perform to the number of horses required to perform the same task. Watt performed simple tests with a horse as it operated a gear-driven mine pump by pulling a lever connected to the pump. He determined that the horse was capable of traveling 181 feet per minute with 180 pounds of pulling force. This multiplied out to 32,580 lbs-ft per minute, which Watt rounded off to 33,000 lbs-ft per minute. Divided by 60 seconds, this yields 550 lbs-ft per second, which became the standard for 1 horsepower. Thus, horsepower is a measure of force in pounds against a distance in feet for a time period of one minute."
This is why dyno readings provide both horse power and torque readings.
