Tuning with an A/F Ratio Meter
« on: February 24, 2013 - 09:57:30 PM »
So, I assume if I have an A/F meter, I just observe the meter, while at various throttle
positions, and adjust the primary and secondary jets on my Holley accordingly?
72 Cuda, owned 25 years. 496, with ported Stage VI heads, .625 in solid roller, 254/258 at .050, 3500 stall, 3.91 rear. 850 Holley DP, Reverse manual valve body.

1999 Trans Am, LS1, heads, cam, headers, stall, etc! Love to surprise the rice rockets with this one. They seem so confident, then it's "what the heck just happened?"

I also used it to tune the adjustable air bleeds as well as the jets.
