I have a 50 shot of wet right now. I use it perhaps once a month for a few seconds. I am not a racer. I don't go to the track. I don't street race. The NO2 is only for my personal amusement. I would like to
upgrade slightly to a 75 to use just as infrequently. Aside from using a one step down sparkplugs setup, do I REALLY need to go the whole 9 yards and tune and get a new ecu etc... I've had the 10lb bottle in my trunk for 4 years and it isn't even half empty. I really don't want to have to mess with the computer if I can get away with using the 75 RARELY. Thoughts? Again, I have no problem getting cooler sparkplugs obviously. Thanks in advance for your opinions.

In my opinion, you should be just fine if you have the fuel jet nice and rich. For sure run the cooler plugs. I would go no further than a 75 shot without timing pulled (aem FIC makes this easy). I cannot wait to spray my car.

He means go up 3 on the fuel with the jets. Like if your running a 25 jet on fuel then go up to a 28 jet to be safe... richer mix.

FYI I've been running a 75 wet shot on my car with no tuning for a good bit now... about 3 bottles and no problems yet. I even went as far to go with a 75 shot nitrous jet and a 50 shot fuel jet, just to make it leaner. But I do have a wide band so I know I'm not going to lean. without a wideband I would rather be save then sorry.

If I tell my performance shop to do so, im sure they will understand what I want. I dont know what Im using on the nitrous OR the fuel jets at the moment. Ill just tell them to upgrade the fuel by three and the nitrous sprayer to a 75 shot correct? Did you go down one in the spark plugs too? Thanks to all!

If your going with a shop that you trust then I would just let them do everything. They should know what they are doing.
