As someone else stated, don't worry about the absolute numbers, the number you should pay attention to is the difference from stock to tuned on the same dyno.

I see two problems with your dyno graph. The first is that the stock pull is not your car and was done months before. While the same dyno, you want to eliminate as many variables as possible. The temperature, humidity, fan speed and oh yeah, it's not your car are all different.

Second, your car only had an increase of 34 ft/lbs of torque and 46 of hp. Those should be around 100 and 85 respectively according to the Dinan website (I already subtracted 15 percent from claims since their numbers are at the crank).

The best would have been to do back to back pulls with your car but even so, your increase in torque and hp are way low.
