I had my truck dyno tested at a "speed shop" for $89. They do 2 passes and you can change things for the 2nd pass. I left everything the same. The only things that were done to the truck were the HYPERMAX 330 HP chip and a K & N air filter. I posted figures of 268 horsepower and 544 ft lbs of torque. Now these are real figures at the rear wheels. If I get a chance I will scan the printout. I have an appointment to get the 5 inch exhaust on Thursday, March 28 and I plan on going back to the dyno 2 weeks after that the see if the 3.5 inch downpipe and 5 inch exhaust increase horsepower. Also if you get a chance take a look at the Hypermax website, they recently moved to www.hypermaxdiesel.com.

I love the big-torque numbers of the PSD. :-staun
