Have undertaken a nitrous install on my 2013 Mustang. My car is a GT 5.0, mt82 manual, 3.73 rear gears with 96,000 miles on the ODO. This car runs at high altitude pretty much always. With nitrous or supercharging, ALTITUDE FIXES MANY PROBLEMS. Keep this in mind as you read on. When you hear that nitrous is bad at altitude know that the Luftwaffe ran nitrous in some of their high altitude reconnaissance aircraft to boost their power by 30% and allow them to outrun those pesky allied fighters. My system is a ZEX unit with the throttle pedal position learn function which did not and still does not work. It is a wet system, install is straight forward but - an rpm window switch and Wide Open Throttle switch are MANDATORY if you like your car. If its your wifes and she knows nothing about this install, party on. My window switch is set to 3300 rpms on and 6500 rpms off. I also have "tunes for life" through American Muscle for my BAMA SCT X4 tuner and am running the 93 octane Race tune with a 3 degree timing retard full range and an additional 3 retard at full throttle. The system is set for 125 hp. At this altitude I suspect my car with the 93 R tune and no timing retard makes about 320 to 330 hp at rear wheels. So, 430 to 445 with a 125 hp shot or, at sea level, 530 or so. With the cars anti knock sensor on watch and the timing reductions in the tune and the ALTITUDE all working in my favor, the nitrous coming on in this car is like being pushed along by a Hellcat. No kidding. Just astonishing. Have only three 10 lb tanks through it so no longevity data. Run 0w20 Royal Purple in engine and Royal Purple Synchromax in transmission. 91 octane pump gas. Stock tires make quarter mile runs kind of silly but have run in the 12s here at 6000 feet with virtually no skills and 73 year old reflexes.
