Worked flawless and seemless. As ytou look at the graph it is very difficult to see that another stage is coming into play at 4200 rpm. I have the first stage coming on at 3200 and that is a quick jump in TQ and HP just the way I wanted. Thats to get in the power quickly. But the second stage I wanted to come in more controlled...and it does as you can see. This TQ line is not too violent and not too drastic. The large HP # you see with a relatively sage tq # is due to the way the controller adds the juice of the second stage gradually the way the users wants. The AF was going way beyond 10-1 off the scale. There is another 50 rwhp jusy from getting the AF inline. We will have to jet UP on the nitrous because we are on the smallest jets in the direct port. So it will likely be closer to 840-860 rwhp when its done. The if the customer wants to jet up he has enough to hit well over 900 rwhp im sure. We will have it completely worked out here in the next week or two with final #s. But I am VERY happy with the NX controller. You cant even tell there is a second stage coming in at 4200 rpm
