Don't let its simplicity fool you. ForzaTune does a lot of work behind the scenes to make an excellent base tune. If you like ForzaTune be sure to check out ForzaTune Pro. It lets you tune for specific cars, tracks, advanced gearing, drift, drag, rally and more ... making even more tunes faster. Whichever you choose you'll be well on your way to better lap times and a more satisfying drive. -- ForzaTune does NOT have in-app purchases, account sign-ups, or time limits. You can make unlimited base tunes for the street or track as soon as you download it. -- FAQs Q: Which games does this support? A: Any Forza Motorsport title or Forza Horizon 2 and later. Vehicles will typically need race suspension, anti-roll bars, brakes, and differentials. In some cases, cars are stock adjustable and you should *not* install a rally suspension. You will also get better results without stability management (STM) and other assists. Q: How does it work? A: Enter weight, weight distribution, performance index, and drive type. Hit "Next" to see your results. Copy those results to the tuning menu in Forza. Follow the "next steps" section below the results to make your tune even better. Take ForzaTune for a spin and see how easy it is to make your own tunes.

Verdict

The call

The clearest difference is review sentiment: ForzaTune at 84% against SIM's 43%. ForzaTune also leads on in-app purchases (none vs 24). SIM's advantage is update cadence (every 2 weeks vs every 2 months) and rating (4.6 vs 4.3). On price, ratings volume, ads and device support there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. SIM sells 24 one-off in-app purchases. ForzaTune asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

SIM holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 149 and 445 respectively. Written reviews complicate that: 84% of ForzaTune's written reviews are positive against 43% of SIM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ForzaTune ships an update every 2 months, SIM every 2 weeks. The most recent releases landed on September 23, 2026 and September 21, 2026 respectively.
