Question about fuel needs, timing needs... what else is there?
ok my last dyno sheet shows that im using all but 3% of my injectors from 5.5k to 7.5k. Minus 3% is where I ended up setting my safc to get 11.5:1 at 10psi. I am now running 11psi have have the tune set to -1% to be safe until i can get back on the dyno.
Im going to run 50 shot...maybe more later. My Wg is ported huge, but odds are it will still creep a pound or two.
The extra pound or so, and the extra hp made my all this will need more fuel then i have right now.
Southcart has given me advice on timing issues... That I should run 3 degrees of retard while spraying. I have been needing to retard my timing a few degrees anyway for the added boost.
So here are my questions................
1. Could I just retard the whole map at the CAS 3 degrees. Do i need to retard more while spraying?
2. Will the cooling effect of the nos allow for the extra pound or two i might see? Im at 11 now... if i hit 13psi my stock TIMC wont cut it. unelss..... the nos cools enough for the problem.
3. Would the correct selection of fuel jets on the nos kit allow for the extra fuel needed? Extra fuel not only for the nos hp but for the extra psi or so ill endup running.
Seeing that i can change out the jets it seems like i should be able to tune it like i can with bigger injectors and a controller... but with jet size alone.
Thanks again.

1. yes you can, but its gonna be -3 all the time, -3 isnt all that much, and its gonna be a tad bit safer at higher boost like that.
2+3, i dunno, nitrous isnt my thing
