OK, so I decided to go ahead and buy a VSM. Why not, right? Now I know how fast my car goes. I have a Nitro RS4 3 with an OS .15 CV-RX and a 2-speed tranny. So far I have reached the 40 mph plateau. But of those who have one, do you find that you just keep trying to squeak out that extra 1 mph when you're running? Trying to get this thing going as fast as possible? Man, it was like a drug the other day. Run....tune....run....tune... Even pushing the temps just to get that fastest run of the day. Just too addicting...
