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?Originally Posted by 94RCSB
Simple: 408 on steroids!
single digits coming soon!
No wideband installed
you should be running a 62N/36F, a 38 on the fuel would be rich, for 100hp you need a 52N/28F
Alright got my jets it is set up for a 125 per nitrous express chart we wi see what it is like on Friday.
only real way to tell with nitrous is to pull the plugs after every pass and read them. adjust accordingly
