It looks to me like the colors refer to the same conditions. In the first data set, the solid black curve is hp (left vertical axis) and dashed black curve is torque (right vertical axis). These have the same numerical value at 5252. The red curves have similar meaning, but for a different setup. In the stock data set, I think that the colors go together once more, but I can't really tell whether the lines are dashed or solid.

For the benefit of the fellow who asked about dynos, they measure torque. HP is computed from the torque as: HP = pi *torque*rpm/16,500. The curves cross at when rpm = 16,500/pi = 5252

The stock dyno curves are in post #7 (looks like three separate runs), and the modified dyno curves are in post #1 (first graph). The second graph in post #1 shows the same hp curves, and the air/fuel ratio instead of torque.

the tq line was where the confusion was; it doesn't normally look like that (it usually drops off aound 4500-5200 depending on the setup). Like Fast FWD said, the dotted black line looks more like the tq line. So pairing up with Black/dotted black and red/dotted read... everything makes sense now.

Thx again.

For the limited mods you have and only 1.1 Bar, that looks pretty good.. Almost identical to my present setup.....
