Make this a sticky please -
My friend Scott Kornish on the Neon.org board wrote this to explain how you would need to set a progressive controller and run alot of nitrous and not blow it up. I've been trying to tell people for years progressive control will allow you to use alot more nitrous than you normally would, I just never could explain in layman's terms.
Anyway, he explained alot better than I could -

To specifically answer your question lets have some fun with nitrous math. NX conservatively states that a typical stock 4 cylinder engine can handle a straight 75 shot with no problems. At 3000 rpms the torque added would be 75hp*5252rpm/3000rpm = 131.3 ft-lbs. So to be conservative we'll say your engine can handle making 230ft-lbs of torque without bending a rod. (Assuming you're hitting the nitrous while already accelerating the car). You want to set up you nitrous controller so you don't exceed this torque limit. At 6000rpms a 125 shot would add 125*5252/6000 = 109.4ft-lbs. You're way safe as long as you set the time on the controller to be hitting full nitrous by the time you're at 6000rpm. I use Desktop Dragstrip to help figure out time in each gear so I know how long to set the build time for. Its kind of a guessing game, but just work your way up and input your data as you go to match your real world runs as closely as possible. Anyhow, now that I have a reliable daily driver, I'm going to test my theory with a 150 shot next summer before I totally change my set up.
