The kit referred to in this post is the "advanced tuning" kit (equal to a stage 3 kit). I would like to know if this kit comes with ??shorter slide springs and slide drilling instructions?? ...and what are the other differences in this 1.7 kit as compared to the standard 1.0-1.1ti kits. I am now considering going with a full exhaust system, and this kit should complement such a setup very well. The DJ setup seems to leave a (small) flat range somewhere no matter what setup I use.
