Actually, the control box is not even on yet.
Just the y-pipe, pipe, can, high-flow air intake, reeds (V-Force) and the secondary weights from SLP. I know a couple of guys that put the different gearing in, one even went out west with us last March, but the sled was a pooch. I was not impressed with a gearing change at all.
I pretty much followed exactly what SLP told me to do and I guess their 100's of hours of testing everything under the sun paid off, they sure knew what to do and what not to do!
