What should I expect?

I currently have an Xcal now, though i will be updating to the xcal2 when it comes out, the only difference really between the two is the ability to datalog w/o the raptor which for some reason is no longer avail. How much power you get out of it really depends on the Tuners ability and knowledge. Kauffmans Motorsports is a perfect example, they were able to eek out more HP than my previous tuner with the same mods. But either way make sure they tune your car on a dyno with a wideband 02. Good luck!

yes the linelock holds both front wheels, installs before the prop. valve so it holds equal line pressure on the front brakes. Very high quality kit. See the post about linelocks. I have posted a pic..
