Ok so i was wondering if i would need to get a tune for a 75 shot of nitrous? I have heard some people say no and i have heard some say yes!

Brenspeed and many users of the zex kit say no. Use premium fuel and your 75 shot should be fine without a tune. Obviously, if you later step up to a larger shot, colder plugs, tune would be good.

If you get a custom tune it would tailer the shot for your car. You would get more power with a N2O specific tune.

I ran a 75 shot with an SCT tune for a couple years. I pulled out 2 degrees of timing when I ran the shot since the tune already had advanced timing.

so would it be good to plug in my sct and retard the timing 1 degree or should i be ok and just leave it alone as long as all i run is a 75 shot.
