first off it accelarates alot quiker than it did before it will pull the front tires good on the 1-2 shift and barely pull the on the 2-3, it also run with my friends blaster till about mid way through 3rd then he starts to pull away all i can say is that i love it and it does unlock some power notsure if the top end is any better but it definetly accelerates faster. Also got a question everyone say top speed on these is 58 mph i only got like 54-55 with the 23 and about the same with the 25s and ive not run it yet with the unlocker. question is why is mine so slow lol any answers lol
