2011 Mustang GT 5.0 6 speed 3.73's
I used my Diablo Trinity 91 peformance tune that came with the tuner and went to modify the tune because the gear ratio was set at 3.31 gear ratio and i have 3.73's from factory. The closest i could get was 3.70 it would not let me put in 3.73. Anyone else notice this? Or is 3.70 close enough?
Thanks for any help.

My other question is about my airaid air intake i wanna take the insert out when i install it and some people are saying i need a custom tune when u take the MVT out. Really like to know what tune to use cause there is 2 tunes on the trinity for the airaid already does one support taking the insert out or not.
Looks like im talking to myself lol... i think i answered my 2nd question with what i found. Looks like the tunes on the Trinity that say (airaid) are tunes that you would use with the MVT insert taken out....Please correct me if im wrong..
This is what i found online:
AIRAIDs new Mustang Air Intake System comes complete with all the necessary mounting hardware and complete, detailed instructions for easy installation. The install can be accomplished by the average driveway mechanic in about an hour. The following photos highlight a typical installation. If you're a 5.0L V8 Mustang owner looking to unleash the hidden horsepower and torque that is sitting under the hood of your car, without the use of aftermarket programmers, then AIRAIDs new 5.0L V8 Mustang intake system is worth checking out.
The DiabloSport Trinity is also very easy to install:
Plug the Trinity cable into your diagnostic port located under the driver side dash.
The Trinity will turn on and boot up to a menu screen. (If the screen does not light-up, then replace your cigarette lighter fuses)
Proceed to installation, agree to the disclaimer, and choose the appropriate tune:
If leaving the MVT insert inside of the intake tube, then choose from the standard Diablo tunes. There are different tunes for different octane fuels used in the vehicle.
If you are removing the MVT insert from the intake tube, then you must choose from the Airaid CAI tune(s). There are tunes for other CAI (cold air intakes) listed but you must choose from the Airaid CAI tunes when you are removing the MVT insert from the intake tube.
You can also choose to modify any of the tunes to correct the speedometer, raise speed governor, and other advanced parameters.
The DiabloSport Trinity will record and save your original OEM software and then install the new tune you chose. You will prompted to go through a series of key cycles and screen prompts during this process.
Total install time for the tuning during the initial installation is about 15 minutes.
