I've been always a racing game addict and started playing Forza with the very first Forza version back in 2005. I only used to download other peoples tunes as in the first years I was only interested in playing Online Multiplayer lobby races and didn't want to deal with tuning at all.

​

It was until Forza 5 that I first started tuning on my own and started to gather all available tuning guides and analyzing available open source tunes from other tuners. I was very proud of my first tuned car that was reasonably competitive in lobby racing - I can still remember the car: it was a 2008 Aston Martin DBS - I simply love that car.

​

In Forza 6 when I started tuning almost every car I drove, I always eventually came to a point where I felt the tuning cannot be improved anymore. Also all cars I've tuned to that point had nearly the same feel on track. That was the point where I asked myself if they are any similarities or patterns in those tunes that can be extracted and reused to speed-up the tuning process for further cars as it was quite time consuming for me to perfecting a tune.

​

Ultimately this led to my first tuning app QuickTune 6 for Forza 6 in 2016, a fully automated tuning calculator that calculates ready-made balanced tunes that don't require any tweaking. In 2020 critically acclaimed successor app QuickTune 7 for Forza Motorsport 7 was released and refined many tuning aspects, most importantly it added track specific tuning. All that culminated in the release of QuickTune Pro in 2023 which takes Forza tuning to the next level with a much better user experience and better tunes out of the box.

​

With the new Forza Motorsport 2023 now being available I was of course curious on how tuning has changed and evolved. This tuning guide is largely based on my Forza 7 Tuning Guide with some updates  to address the changes that have been made to the tuning mechanics in the new Forza Motorsport. These changes are marked with  New  or  Changed , so you can easily spot what has been changed as compared to Forza 7.
