Is there anything this small? I mean this thing is nice for those smaller cars is there something better i hear alot about the keyence stuff but never seen one run. I wouldnt have any other speed control inless its this small i mean im not sure but i was told this was the best on the market by far and has more puch to it. TRUE? I know it beats the old gt7... Anyone tried the mms3 from corally or the keyence? just woundering if there worth the money of takin the current gtx off the car to get faster.
