A/F ratio's
for safe peak power/torque 13.0 - 13.1 is what we shoot for on a hi compression non turbo, be sure the sensor is reasonably fresh so you get an accurate rate and make sure that its not pulling air before the sensor for a false reading.

Sorry to hijack, Mike I sent you an email through JBRacing....
I am showing 12.8 on my 3.4 where we made max power. Same reading on both the LC-1's I have mounted in the car and the sensor the shop had in the tailpipe. how much is this affected by intake temp, or is it at all?? Cheers
