Is NOS cheating???

[Power]

I know that I'm going to get hammered by a lot of you guys on here for this one. Does anyone feel that NOS is cheating in anyway. It may be just my opinion but I've never liked NOS for the simple fact that it makes cars beat faster cars that don't have it. It seems to me the cheaters way of beating a bigger, stronger engine than your own. I'm not looking for flames and not trying to start anything with anyone here, just want everyones opinion on it. Keep in mind I'm talking about street application only.

1966 Baby blue Coupe, 289 w/ man. 3-speed, nothing special but the fact that it is my first mustang. I am a former import guru....no more.

I've never run it except on the street, it has new wheels & tires, new exaust, and that about covers it. Looking to change a lot in the future including engine. Any ideas are appreciated.
