    Cammed 5.3 with nelson performance 91 tune

    Hoping someone who knows or one of the gurus themselves will chime in I got my 5.3 with vinci cam 3200 stall and 4.11 with 91 octane tune. I have my nitrous express shark nozzle with a 62 nitrous and a 38 fuel which is for a 150 shot but it is rich on the fuel side. Wondering if I can spray the just the way it is with my tune I got or if I should back it down to a 100 shot at the track.

    whats the AFR running NA? if the AFR is fat spray it 100 then if its still fat spray a 150 but dont change the fuel jets just the nitrous jets, i take it you do have a wideband?

    you should be running a 62N/36F, a 38 on the fuel would be rich, for 100hp you need a 52N/28F

    only real way to tell with nitrous is to pull the plugs after every pass and read them. adjust accordingly
