Yeah a 0.4 difference between NA and using the juice isn't very much especially if thats with a 75 shot. Thats really odd?? but thats good info, I find my car to be faster than it is at the track too!

But thats just my wishful thinking, but I know what you mean the street and the track are two different things when accelerating forward to gain some distance on the street from the car beside you or when your racing at the track.
Thanks for the info again, I guess a nitrous system is in order for me, I want an automatic bottle opener too so I can use it when I need it and I don't have to have it open all the time when I'm at the track<wink wink>.

Plus whats a reasonable price for the NX kit and GenX. Just by going off there website its ~$1000, is that reasonable??
