In case you dont know how to see if the throttle is being opened. Take off the air filter and look down into the engine. You should see like a metal plate that is only open about 1.-3mm. Then when you pull the throttle all the way it should disappear.

IF this dose not work check your spur gear. If it is fine then move car back to factory settings and retune. Then if stil nothing maybe its time to take apart the tranny.
