What should air fuel ratios be when spraying.
 

I have a 99 C5 air filter and exhaust and was wondering what my afr's should be when spraying a 100 or 150 shot on a wet kit.

It varies; it's really up to you. The richer you are (up to a point) the safer you are, but the richer you go the less power you'll make. I would not go much leaner then 12.2 ish and not much richer then high 10s on that size shot.

I like to run mine on the safe side. 11.0 to 11.5. :)

Anything under 12.0 should be safe. I would rather leave a few ponies on the table then lay the $$$ on it!

Same here, makes good power and still on the safe side.

Cool thanks for the help.

11.5 to 11.7 depending on where at in my curve.
