No two machines read the same and everyone thinks theirs is correct. I don't pay hardly any attention to the horsepower when I am tuning other then to see where it has changed and how much. The numbers are just numbers to me, although I know people get hung-up on them.

We try and keep these machines as accurate as possible. Things are constantly changing. Things as simple as a bearing getting wear and adding more drag can effect the results slightly, and that is the reason why we spend as much money on maintenence on these two dyno's as possible.

What are ALL the mods on your car Waldig? If it is just the CAI and gasket matching, with no other modifications and you are making the same or more power according to your dyno runs as guys with CAI, Pulley, full exhaust, Computer reflash, ect. then I would have to question your numbers being high, just as Steve questions his being low. Just curious.

I along with ANY OTHER dyno owner/operator can make these machines read higher or lower if they want. What benifit would I have to making them read LOW and having people dissatisfied? Much more to gain by turning them up and showing people what they want to see, whether its right or not.
