I have no time yet to run in race track , but I just have new pulley and tuned so I test it by set digital milage at zero and then take off. After 0.2 that's mean 200 m. (that's all the clear distance close to my home) I got 87 mph so the question is, Is that fast or slow? Better than stock or not? And if I run 402 m. what proximately time should be? thanks
