NEW AFR Gauge what number would be good I have the TNT 150 shot wet kit & the nano system on order... It's a old kit.. I heard those thing run really rich.. Do you think I could stay with the 150 fuel jets with the nano.. Also a buddy of mine said I should try to get my AFR around 12.0 on spray.. I would like to know the highest afr number I could get away with.. Nano said I would have to up the fuel jet... I really don't want to do that.. THANKS EVERYBODY for your help.. It's been along time.. economy and so on.. Thank GOD I didn't have to sell my car like 2 of my friends have...

Yea can't really go by only afr numbers. I am a newb to nitrous but can tell you this READ YOUR PLUGS!!!! On my 100 shot and a 12.2-5 afr it was still rich. The only way you are going confirm what your afr should be is making a pass at the track and reading the data you obtain from from the plugs. Sure it is a hassle but if your only spraying based on afr numbers you will never know if 12.0 is still rich without seeing what your plugs say. Many people spray based on afr's and it works, but I've been hanging around the nitrous section a couple months now, and have learned that getting the most out of your kit is a proper tune up. Just my .02 good luck.

Wideband is a good tool to keep you in check all the time. Something that you have to think about with a wideband is where your placement of the sensor is. If it is reading one bank then you will not know what is going on with the other bank. If its reading in the y pipe you will get a good average of the motor but harder to pin point one problem cylinder. Reading plugs will get you on information on each cylinder and that is why most people will say use the wideband with a plug check as back up.

You will most most deffenitly have to cut the plugs to see your fuel ring. I personally didn't read all the plugs I only pulled 7&8 which is wrong to do, at the very least you should pull 5,6,7,8. I don't know if you have a/c still in your car, but that would make the process much longer. If you have access to an open road go for it. Pull all the plugs cut them up and post pics for feed back.
