glad to see I'm not the only one thinking this BS seemed fishy! I'm trying to plan out what mods are gonna get done to the GMC, and the 10 hp gain from a catback and K & N cold air seemed reasonable, but not the 2nd report!

(in-house, partial testers will help too)
But claims of a 55 hp increase over stock is pushing the needle on the BS meter just a tad.

I believe them numbers so much that I just orded a set of MSD for my truck. The Granatelli wires were like 150 dollars though summit and the MSD were 66 dollars. I guess they could have made 50 horsepower if it was the original wires and air filter off a truck with 300,000 miles on it?
