NX shot leaning out a/f,do Ichange jet size?
just dyno'd my car with my NX wet 75 hp shot,
the cars mods are CAI, pacesetters and true duals,
it's an 02 A4 z28, and it
put down 329.8rwhp and 339rwtq at a mustang shop
the air/fuel ratio was 12.9 N/A,
on the spray
it put down 393rwhp and 430rwtq but the air fuel
ratio went to 11.9 on the first spray run and 12.0 on the other nitrous run,
I was told I can just change the fuel pill to make run richer,
I'm using the 75 HP pills right now (41F and 22N i believe)
so How much higher on the fuel pill should I go?

Ditto on the jets sizing, think its backwards. Now if you were LEANING out, as in going from 12.9afr NA to say 14.5 afr on spray, then you would have some issues. Going from 11.9 one run to 12.0 the next is nothing to worry about.
