Just got back from the Mustang Dyno today, and the numbers for my 03 Vert seem respectable...However would like to get some comments on the AFR they logged...

Max Rwhp = 463
Max Torq = 491
AFR: 11.9

Note, the car has a few bolt on mods, K&N CAI, Corsa Cat Backs exhaust, BBK Throttle Body, and tune from Specialty Performance.
Do you think the AFR @ 11.9 is normal for this set up on a 2003??

would like to hear the forums thoughts before I look to change anything..
