1998 camaro lean on nitrous Hey guys, I have been at the dyno all day today. I have a 1998 camaro with a 6.0, Ls 3 heads,Ls3 intake, a 92mm edelbrock throttle body, and I was told that it had a 585-585 lift cam? I'm kind of new at having a fuel injected race car. Anyway, on the dyno the car pulled 348rwhp at the most. The af was perfect. We added some fuel and retarded the timing 4 degrees (20 btdc), to compensate for the nitrous. Upon trying to shoot 100hp dry shot the af went way lean. The operator attempted to add fuel several times and was still way too lean. Any help would be greatly appreciated.

Start with plug gap, too much cylinder pressure (air
mass) and your coils won't punch through the gap.
Then all the unburned mix will hit the exhaust and drive
the wideband nuts.
Of course you need to be sure your fuel pump and so
on, are actually capable of providing any "added fuel" -
just because you say it, doesn't make it so.
