This is a modified version of the stock I3 on the Ibishu Pigeon. The torque curve now looks like this: "enginetorque":[ ["rpm", "torque"] [0, 0], [500, 58], [1000, 65], [1500, 79], [2000, 90], [2500, 107], [3000, 63], [4000, 55], [5000, 45], [5500, 30], [6000, 20], Disclaimer: there is a very good chance that this will make your vehicle a LOT easier to tip. Happy Travels!
