actually.......scramble boost is a high boost aside from what is set. So if you run 8 in 1st, 10 in 2nd, 15 in 3rd, and 18 on up, because of how you have your boost controller set up. Say scramble is set at 22 and triggered by a switch irregaurdless of what gear your in. It's a, "damn this dude is starting to pull on me" button.

What you're looking for is a progressive nitrous controller, you can fully tune your nitrous with one. It's like a boost controller, you're pulsing a solenoid at a set duty cycle based on RPM and gear or what ever the imputs are. You can easy into it to prevent wheel spin, and you can start it eairlier because you can limit how big the initial hit is.
