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?

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

Will the speedo typically read faster or slower?

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?

My 2007 Mustang V6 has an Airaid Cold Air Intake, Magnaflow Cat Back Dual pipes and a Diablosport High Performance (Firm shift) tune. If I swap out the gears with 3.73's, will that effect my tune?

Kevin, thanks for your reply. I don't have the option of using an "Airaid" firmshift tune. Are there intsructions on how to export my tune and e-mail it to you? As for the venturi...should I remove it?

I have the cables...I just need some direction from you guys on how to do it (newbie ...lol)

as far as I know, everything is set up as indicated.

I have an 07 Mustang 4.0 V6 with the Airaid Intake and the Magnaflow Cat Back Dual pipe system. I downloaded the 91 Octane Airaid Performance tune and I am finding a big hesitation off the line. Should I re-program it or try something different. Also, I have been reading some of the posts and I am ...

I currently have the Airaid 91 Octane Tune installed in my 2007 V6 Mustang. I will be adding the Magnaflow Dual Cat Back System, will I have to change anything with my Diablo Tuner? Also, does this tune shut off the Traction Control?

Just so you know, this was an American car which was remodified with Canadian standards. We must have DRL here, also, the miles have been switched to km's and the speedo dial has been changed. Maybe, there was something in the disconnect that triggered this to reactivate.

Great call, the disconnect did it! Thanks guys!

Just received my new predator. (U7145) After installing the Airaid Kit Tune, I lost my daytime running lights (Mandatory in Canada) Any thoughts? I am tuning a 2007 Mustang 4.0L Convertible.
