I have the Whipple and it runs great! Sorry that I don't have any dyno figures but there is a huge improvement in performance. Whipple advertises an increase of about 135 hp. I was one of the first to use the Whipple on the H2 and had some problems with the torque management and had to send the PCM off to Ed Wright for programming. I also have Edelbrock ceramic headers and a stainless catback exhaust system.
BTW I have had a whipple on my '94 454 Suburban for a few years and it runs flawlessly.
