I just threw the NOS in there to try to save some bucks for you,it is a lot cheaper than a super charger

Nos is not really a bad thing. It does basicly the same thing the superchargers do. It gets more air in the cylinders.

But acutally I do agree, I would rather see other methods. NOS bottles can go empty when you want them to be full.

The most you may want to change is the maximum boost. On the street limit it to one pressure, on the track raise the pressure. Just be sure the engine can handle the increase.
