The truck only has 20 miles on it and its already for more horse power upgrades. The new owner had the dealership install a Magnuson 2300 supercharger kit on it, but requested that the crew at TW perform the dyno tune. This is sure to wake up the direct injection LT1.
After a couple of weeks, the truck is back for more horsepower. A new cam was installed and then tuned on the dyno. How about a whopping 511 h.p. at the wheels!
