Nitrous experts and tuners timing ? Please help Mods are in sig. I am spraying 150 shot with br8efs plugs with 10.5 com ratio with 91 oct. pump gas (12.7 afr ). Does 22* sound like too much timing for my app. I am learning to read plugs I think i am getting close. Am I in the ballpark? Where is it normally for this combo? For example would it be in the (16-18) (18-20) (20-22) (22-24) range? I know every motor is different but when you do this all the time you know about where it will end up. So could you help reassure me i am not way off. Thank you.

It was good talking to you again and as per the phone conversation you're in the right direction but we do need to get a good read on a fresh set of plugs to ultimately determine where we on the timing mark.

I am running lean using .062N .031F (plugs are reading but the wideband reads 12.7-12.5 at start of run and 12.2 end of run) jets the kit recommends is .062N .036F if i run recomended jets the wideband reads 10.8 to 10.5. That is why I started messing with the fuel jets next time i am out will get a plug reading. Do you vary from recommended jet sizes usually to get it dialed in? I am using a shark nozzle (58 ffp).

Chris from NX, the nitrous jet sticky says .033 for fuel but your website says .036 for fuel on a 150 shot which one is correct? I have a (.033 and .036) I am going to try next time out. And the BR8EFS plugs are working.
