Ran into a few problems with my Slayer Pro. Got it new about a month ago, and since have had a blast bashing and racing it with my buddies. We recently built a track, and I had been looking for some upgrades to make it more competitive around the track. The guys at the local hobby shop recommended the center diff and rear brake kit. They gave me all parts for a Revo, which I thought was odd but they said almost everything was the same besides the suspension parts. I installed both parts, and took it out to check it out. After warming it, under full throttle it ran like crap. It was shifting very fast into second, and seemed like it would hit maybe ~20 mph and stop accelerated. The RPMs would stay the same, but it wouldn't get any faster. I tried adjusting the shift point to shift later, maybe 1/4 turn, and it shifted later but speed was still approx. the same. I took it back apart, and one of the rear brake screws had come undone, causing drag there. I'm wondering if I need yo adjust the shift point more, if I need to lube the gears, or of I might have gotten the wrong center diff causing a lower speed. I know they sell a slayer center diff, but from what I saw it was for the 2wd version, and I should be fine with the Revo 3.3 one. Any help would be great, sorry in advance for any typos as I am on my phone.
TL : DR - Installed Revo center diff on Slayer Pro, car falls on face when under hard acceleration as if its hitting a brick wall.
