okay i have the nitrous express nxl direct port kit 20200 and i just went from 90 to 150 shot jets when i put it on the dyno it pegged the a/f ratio at 10.0 and then we took the primary injectors back 20% and it was still pegged at 10.0 i just had the bottle filled pressure was around 1100 were the bottle heater shut off fuel pressure was at 45lbs the nitrous jet sizes the gave me were 31nitrous and 18fuel too me it seems like i dont have enough nitrous jet cause im making the same power as my 90 shot jets but the a/f ratio is pegged at 10.0 and i should be getting alot more power any ideas would help does anyone know if these jet sizes are correct for a 150 shot? ive called nitrous express and talked to 3 different people and they all said it was right but it cant be. maybe my nitrous line has a clog in it? anyone have any ideas?

What jet sizing did you use on the 90 setup?

gearhead16

26 nitrous and 12 fuel was the 90 shot

start dropping the fuel jets down in size til you see the results you are looking for

i was gona try that but i remembered there a screen right before my solinoids and i checked it and it was half clogged so i cleaned that out im sure that was a problem. im also woundering if maybe the screen is too restrictive for the 150 shot cause they only sold up to a 125 shot for my kit but they made this 150 for me. any other ideas would help im waiting for a new clutch to come before i bring it back to the dyno
