My neighbor has a tornado shockwave and we cant seem to get it running properly. after we went through brake in process it just never seemed to run right. we've tuned it from 3 turns out and down to 1 1/2. The high speed is fine and we keep trying to work with the low speed. The car takes off really slow and has bog but once the rpms get up it runs great in top end. Went the car is on a stand it has a quick throttle response and sounds good all through low end to top. When we put it on the ground, if we hit the gas 3/4 to full throttle it with bog then slowly gain up to high rpms. it doesnt do that on a stand, only on the ground. I know how to tune but it just doesnt seem to want to run right. its not getting to hot the temp is fine. Could it need a better clutch or something like that. just an idea since its much better on a stand then the ground. any suggestions??
