Forza Horizon 4 Tuning

So I have Game Pass… Specifically at the moment for Forza Horizon 4. I love the game but want to get deeper into it. I was wondering if there was someone who would be willing to kind of give me a rundown of tuning. I’m fairly decent at the game… But beyond using the upgrades, I honestly have no idea what the fuck I’m doing when it comes to tuning. So is there anyone who would be willing to work with me and kind of help me understand what each setting does? Or have any references (YouTube videos, articles, maybe even tuning calculators) that they would recommend to make the dive into this slightly less confusing?


None of us really tune. We just race stock cars for the most part. The only thing I ever tune is gears for drag cars or I just get a tune from the marketplace.

I haven’t tuned anything in 4, but in 3 they had pre-made tuneup you could add to your car…I used this mostly in 3.

I buy the tunes off the marketplace. I look at the class I want and check for the stats I’m looking for. Which is usually handling and braking as I need all the help I can get.
