    Nitrous on a 93 octane N/A tune

    I just finished the nitrous install in my 5.3 Chevelle. It currently has a 93 octane tune from Nelson. Does anyone have an idea of how much I could spray? I just want to make sure it all works.

    It's not recomended really... But I did it for a long time lol! I ran a 100 shot with no issues and probably could have gone bigger... Just use good fuel and make sure you check the plugs

    Put in colder plugs and go with a 100 shot. Spray for a gear, shut it down, pull over, check plugs, adjust jets.

    For a 100 shot, he only cuts 3-4* so that's not a huge deal. Most kits recommend running it super fat during setup anyway. I went up like 4 sizes on the nitrous and left fuel alone, it's STILL a lil rich.

    Just got done playing with it. Running a 100ish shot and it's working pretty good. Probably a little fat with .048 N and .028 F, but the plugs look good.

    For some reason bottle pressure won't go over 900, screw is all the way in on the sensor too. Got a lot of bugs to work out...

    You're spraying like a 170 shot, right? How often do you spray it?

    ya around there.

    Think I went thru 1 bottle at 100, 2 bottles at 150, and 2 bottles at 170ish

    I took the bottle/tune out for winter, but plan on going up to a 200 after I get the walbro in next spring
