InstructionsInput the Basic Information on the left. The Boost will be calculated automatically.If your car has only one turbo, leave both the Turbo_1 boost values (max_boost and wastegate) = 0Its recommended to start modeling the Turbo without the Wastegate, so you can match ingame, by trial and error, the turbo lag, making sure that its max boost is at the expected RPMYou can replace the torque picture on the bottom left with your car´s dyno graph picture so its easy to see.Input the torque values, either in kp, ft-lb or NM and adjust the drivetrain loss if needed. The formula will extract the boost from your torque curve and will generate a power.lutAdjust the Gamma value, so the initial boost curve matches the real car and fine tune your torque curve manually.Torque curve should never start with 0NM of Torque but should end at 0 at max revv (not Limiter revv)

Its recommended to start modeling the Turbo without the Wastegate, so you can match ingame, by trial and error, the turbo lag, making sure that its max boost is at the expected RPM

Input the torque values, either in kp, ft-lb or NM and adjust the drivetrain loss if needed. The formula will extract the boost from your torque curve and will generate a power.lut
