I haven't ran the system anywhere but inside so far becuse the weather in IL. sucks this time of year. I guess i'm just excited that i don't get the glitch anymore that plaques one certain section of our track. Alot of people get hit by it and as everyone knows glitches suck!! so with the spek. so far so good. I bought the M8 just so I could have the spek. I had to turn down the speed of the steering becase it was super fast. I had xr3 befor the M8 and never ran the M8 because I bought just the trans. and module so that is probably why I don't notice anything being slower because the M8 is fast to start with.
