Default Please look at my A/F ratio

This reading was taken after HOT cats. Is the 14.1 reading OK. I have been running with this same tune for 2 years now. Gas milage is great

Without nitrous: 14.1

With nitrous: 12.7

Yea roughly between 65-95mph my AF ratio is 14.3. Horsepower between 65-95mph dropped slightly also. I will soon have the A/F ratio adjusted down to 13.00-13.7

My nitrous run is OK, but after I richen the A/F ratio @ computer I will have to lean the nitrous fuel jet one size smaller before shooting nitrous again.

Too risky. Your best bet is to install the 30 lbers and dial it in exactly. Too expensive to replace the motor.
