"One of the best, if not THE BEST Forza tuning assistant on the PlayStore. In comparison to ForzaTune 6 this app seems to reliably put out better tunes honestly. The simple UI for me personally is a plus but F6 has a clean UI. I like this app a little more because you can choose which upgrades you have which is lacking in other apps."

"I'm known as Caesars Wrath on Forza Motorsport and I rate this app 5☆. It's plain, simple and easy to use design, will have you a tune ready to use in seconds. After testing myself I can confirm that it will produce lobby ready tunes that are reliable. As always a knowledge and experience in tuning, will help you get even more out of it."

"I've been tuning some of my cars with your calc, it works very well even beat some of my PB times. [...] you really have the muscle car tuning down, love it. Thank you very much for the time you put into making this available, well worth it and I hope more people take notice."

Q: Why do you claim QuickTune 6 is a "Professional" Tuning Calculator?

A: Because QuickTune does not use a generic base tune for all cars like existing tuning calculators. Instead it uses a specific base tune for each car type and drivetrain. There are about 40 car types in Forza Motorsport 6, each available in average with 2 drivetrains which makes it up for around 80 bases tunes. With that approach QuickTune can calculate perfectly balanced tunes for each car that don't need to be tweaked afterwards and rival tunes from the most capable tuners.

Q: What is the difference between "Standard" and "Balanced Aero" settings?

A: "Standard" settings are calculated Tune settings based on the provided as-is front and rear aero levels. "Balanced Aero" settings adjusts the rear aero level based on provided front aero level and the cars weight distribution to have a balanced front and rear aero during cornering. If the balanced rear aero level exceed maximum allowed rear aero the front aero is reduced instead and rear aero is set to maximum. Similarily when balanced rear aero is below minimum allowed rear aero the front aero is increased and rear aero is set to minimum. "Balanced Aero" settings are only available if front and/or rear aero kit is adjustable and balanced aero settings can be set within allowed min max values.

Q: Why do calculated ARBs and spring rate values don't match settable in-game values?

A: QuickTune cannot reliably determine in-game fraction digits for ARBs and spring rates. Therefore ARBs and spring rates are provided with 3-fraction digits. You need to set it to nearest in-game value.
