2006 Mustang GT Conv.
Roush CAI
Flowmaster axle back exhaust
U7140

I am told the Airaid tune in the 8r38 revision is written with the insert out of the CAI. Can you give me some idea what the A/F ratio is with this tune ? Also am I correct in assuming this tune is for 93 octane? Thanks!

It should be around 12.5:1 at WOT.

Thanks

91 octane is about the highest available in my area. Assumung this tune was written for 93 octane, should I retard the global timing 2 degrees ? Thanks!

Yes, -2 on global spark.
