Depends on what gearing you have, but generally a numerically higher gear will show lower results on a dyno. For instance, if you have 3:42's stock, and pull 300 hp, put 4:10's in, you might pull 290-295 hp.

It will usually show lower because you are not dynoing at a 1-1 gear ratio anymore. But its not that much and depending on weather and condition dynos can vary by about 10HP anyway. I wouldnt care if the gears showed me losing 40HP the car is so much more alive with them.

I thought it was the other way around
