I was just wondering what a bolt on lt1's A/F ratio should be at. At idle, part throttle, and at WOT. Just wanted to know that way i can find out how rich i'm actually running.

 

At part throttle, the PCM will tend to an AFR of 14.7... theoretically. This will sometime fluctuate because the PCM will compensate for different factors that might affect it, but it should be close to that.

A stock LT1 tune will be around 11.8 for wide open throttle, but some bolt ons will change that to leaner or richer... how and which one will affect your car is hard to tell without dynoing on a wideband, plus each car is different so it may act a different way after a specific mod.
