Jetting change? AFR on the dyno is 12.8 NA, and 11.6 with 27 gas and 52 nitrous jet.... Should I go 1 size smaller gas or 1 size larger nitrous jet? No chance to get back on the dyno.... Hope to get to the track for an event this weekend...
Since you didn't mention otherwise I assume you're running pump gas, proper plugs, timing, etc....With that said I wouldn't want a/f much leaner personally, but if I did I'd start with a 25 or 26 on the fuel and go from there
Same thing happened when I dyno'd my car. The a/f was super rich so my tuner said to get a smaller size fuel jet and monitor it on my a/f gauge the next time I spray. So what did I do...I just upped the nitrous jet lol!

What is total timing and what plug are you using? If you want to clean the .052 jet up then you need to pull fuel out. What is the combo? What fuel? I can tell you that is a fat spread though.

BR7EF plugs, 27 fuel.... Going to try a 25 fuel... If that gets me to around 12.1 ish I'll be happy, if not then maybe a 24.... As recommended by the NX guys...thx for the replies..... T&T tomorrow, and event on Saturday we'll see how it goes....
