The truck is equipped with American racing long tube headers and high flow cats, we used a Diablo sport tuner that was supplied with the procharger kit.
I would still recommend a dyno tune for verification of the box tune from procharger. However this customer was on a time crunch and we couldn't get it on the dyno.
+cesar Castillo Based on other dyno runs I have seen with similarly equipped trucks it should make around 435whp. We just added another 100whp with the addition of ported heads and cam and will have it on the dyno in the next few weeks.
Tony Gonzalez no, factory ratings are flywheel horsepower not wheel horsepower. At 435 whp the truck is approximately 522 flywheel horsepower. A 127 horsepower increase. This truck also had ported heads and a cam added later and made 516whp.
