    I have a Zex and I am running a 125 shot..Running the 54NOS pill and just put the 24Fuel pill in..I have the Window Switch set to spray at 3500 and off at 6000...What would be my best settings...I just logged my A/F and it is around 11.5 ..My bottle pressure would not go over 800lbs and 3rd gear still seems to not be pulling well...I will log for KR soon...I logged Friday N/A and was getting between .5-1.5 KR around 4700rpm and 5800rpm in third.I then talked to Dave at B&G and pulled 1degree of timing....If I still have KR N/A after I logg I will add the 1degree of timing back(bad idea???)..All help will be appreciated...THANKS

    I'm not sure what the question is?

    1) Ignore the KR
    2) Lean it out (start by subtracting 2% fuel)
    3) Change the window to 3000 on, 6500 off

    Thanks ..I was looking for best Window Switch settings... .5-1.5 KR is acceptable?My A/F was 12.0-12.7 N/A..but since I pulled 1degree of timing it seems to have went to 11.6-12.2 N/a ...Should I put the timing back? You do know Jeeps shift out of 1st at 5900 and 6200 after 1st gear...Thanks

    JMatt from what I have gatherd best A/F ..N/A is around 12.5 and on spray is 11.5...am I correct?..And is .5-1.5 KR acceptable N/A and on spray...Window Switch settings should be through the entire RPM range but not below 3000rpm?...Thanks

    You said you were around 11.6 on spray. Aim for 12.0 on spray.
    Yes - I know when Jeeps shift. Set the window switch higher than your shift points. Setting it below the shift point doesn't help. As soon as the rpms start dropping, the nitrous turns right back on anyway.

    With a 100-125 shot, 3,000 rpm is a nice safe RPM to start the spray.

    Don't go below 2500 ever, and I wouldn't go down to 2500 unless I was only using a 100 shot.
