I just installed a wideban and we just tested a 150 shot and used a #62 nitrous jet and a #57 fuel jet. I have stand alone with 104 oct at 10psi
result was 10..8-11.3 afr and timming about 20deg is this ok or too rich?

 

rich ... shoot for 12.3-12.5

 

You're WAY heavy on the fuel. Probably need about a 40 to 38 fuel jet with a 62 nitrous, providing you're on stock 60 psi fuel pressure with the standalone..... that info would be helpful to make a good reccomendation on how to fix the problem.

 

he is on 10psi of fp on the stand alone

 

My fuel pressue 62lb on gauge and my syand alone has low pressure spring 10psi I first tried #42 fuel and car and was cuttin out and not hard hittin , when i put the # 57fuel in , it hit real hard and no missing maybe ill try a #52 ive hered that 11.7 is ideal so thanks for info
