I haven't installed my kit quite yet, it will have to wait until I get back from Iraq. But I plan on running a 100 shot. I had it dyno tuned a few years ago for the H/C setup, but don't remember what the timing was. I'll have to get it re-tuned before I hit the spray just to be safe. I'm adding 39lb injectors, and a FAST intake as well so I needed to have it tuned again regardless of nitrous. The timing will not correspond to the nitrous directly unless you have your own tuning software to switch between an NA and nitrous tune. But from what I read it's not a big problem, and you just run slightly richer NA until the the nitrous hits. With a good tune everything should run real smooth.
