2007 Mustang V6 - Modifications

[titleistmover]

My 2007 Mustang V6 currently has the Magnaflow Catback dual exhaust and an Airaid Cold Air Intake. I want to add 3.73 gears with a BBK 70mm Throttle body. I have programmed the High Octane firm shift (Airaid) tune. Will this need to be adjusted for the new mods?

You should be able to adjust the canned tune for the 3.73s, but the throttle body is probably gonna need a custom tune.

OK...can you expand on this...what should Ii be prepared to do?

[Vas@Diablosport]

Well, you should be able to go into the "modify parameters" section on the predator and adjust your axle ratio in order to correct your speedo for the gears. As far as the throttle body goes, any modification that changes airflow on 05 and up mustangs will require custom tuning. Follow the link below to find a custom tuner in your area that can create a custom tune for your vehicle.

I understand how to change the axle ratio, however, I am uncertain on my shift points (this is an automatic) what kind of adjustment would I need to make?

[Vas@Diablosport]

Shift point adjustments are going to be based on your preference. Trial and error. Make adjustments till the drivability of the vehicle suits your driving.

Shift points are based on RPM which is not going to change with a rear ratio change.
Just leave them alone unless you visit a dyno to get the best RPM for shift in each gear.
