Again if you read it says " run them on their truck" meaning both of them, or three or however many you want to test, and when you dyno are you making sure the dyno is warmed up, and the outside temp is the same, and the truck is running the same temp as the first run, true there are alot of variables, I just dont believe everything a dyno tells me, and im not mad just giving my opinion. Slap any of the CAI's on the market on your truck and I would put money that they give about the same gains. We arent talking about a super powered drag strip queen, its a truck.
