But thanks to this app I’m having MUCH more fun with the cars in my garage! **Developer response:** Thanks a lot! ### 5/5 — What an awesome app! *2022-01-04* A little late to the party but H4 is cheap on sale nowadays! I’m not a car guy at all, I barely even play racing games, but after reading online about how tuning can actually significantly affect the quality of your driving experience I felt that I was missing out on some cars by disliking their handling when it was likely fixable through tuning that I didn’t understand. Actually found this app through the developer’s very thorough and knowledgeable guide on Horizon 4 tuning, but after a few pages my head began to spin and I tapped out to use this tuning app instead, and it’s brilliant! I feel like I’m cheating, but after using this to tune my Baja Bug for snow rally, there is a noticeable improvement in the quality of the handling and I couldn’t be more excited to tune my other cars! Lots of options and your tune is likely only as good as your accuracy at selecting the settings for what you desire. And any true beginners like me don’t be a dolt and fail to notice that the horsepower and other settings are text entry, they’re not just telling you your horsepower and weight etc., you need to type those details in to get a correct tuning! Definitely worth five bucks, especially seeing how much work went into the tuning guide on the dev’s website, thank you for your hard work! **Developer response:** Thanks a lot for your thorough review, this is much appreciated! ### 5/5 — Fantastic App for Quick Tuning *2021-12-10* I’ve used this app for a long time now and finally decided to leave a review as the new version for FH5 has been released. I appreciated how quickly new cars were added into the app as they were released into the game as well. I’m looking forward to using the new version for FH5! **Developer response:** Thank you! ### 4/5 — Forza 5 Update *2021-11-09, version 59.0.1* Will it get a FH5 update or do I have to spend money on another app? ### 5/5 — Excellent! Simple *2021-09-26* Knew nothing but this app does everything for you. Also, I am starting to understand it for myself which I didn’t think would happen with such a fool proof app. I’d buy that for 5 Bucks! **Developer response:** Thank you! ### 5/5 — Great app would wholly recommend *2021-03-12, version 50.0.1* This app is an amazing bit of kit and I would I highly recommend it. I started tuning on this app and when I did so I had absolutely no idea what I was doing, it has given me the ability to be able to know what my car is missing and tweak accordingly. It’s extremely easy to use and has a wide array of extensions to get the best out of your car, whether it be racing, drag, drift, dry, wet or snow quick tune H4 has got what you need. The support and regular updates make this an unmissable investment, what are you waiting for ?!!. ### 4/5 — Good *2021-02-16, version 47.1.1* Only problem is that I race 1/4 miles and it’s not the fastest possible tune ### 5/5 — it’s still a great app *2020-09-29* Do you think you can try to improve the drag racing set up cause I use awd on most and I’d like if it can be a little more four wheel drive so I can get the grip needed thank you for looking Over the review it’s still a great app **Developer response:** Thank you! I’ll look into improving AWD drag tunes. ### 5/5 — Ummm kinda confused *2020-07-23* So, I put in the credentials of my custom 2017 zl1 and I had a previous tune on it that I enjoyed but I am very new to tuning. I used the tube the app gave me after the calculations and it actually made my car slower? Please help? **Developer response:** What do you intend to do? Going for high speed? Then you should use tune type Drag. If want to tune for actual racing try the Speed preset. ### 1/5 — Nonsense Tuning *2020-05-31* I know pretty well how to tune in FH4, just wanted to evaluate my tuning formulas and found this app really nonsense for all types of tuning that it offers. I suggest to try Forza Tune 7 app for tuning, not perfect but much better than this one. Sorry developer, I hope you work harder and improve the app. ## Frequently asked questions about QuickTune H4 ### What does QuickTune H4 do?
