Questions, answered straight.

Is this safe? Can I get banned?

No ban risk — it only listens. Slipstream reads Forza's official "Data Out" telemetry broadcast, a feature built into the game's own settings menu for exactly this kind of tool. It never reads or writes game memory, never injects code, and never automates inputs. You type every tune change into the game's menu yourself.

Does it modify my game or files?

Never. It's a one-way radio: the game broadcasts, Slipstream listens. Nothing is sent back, nothing is touched.

What does it cost?

$4.99, once. No subscription, no unlocks, no recurring anything — one purchase, yours forever. There’s a 7-day money-back guarantee with a one-click refund if it’s not for you. (Heads up: the launch video drops with the first 25 keys free — first come, first served.)

What do I need to run it?

A Windows 10/11 PC. No account, no internet connection required. Playing on Xbox console? That works too: point Data Out at a laptop or PC on the same Wi-Fi and Slipstream reads it there. You can also open the live display on your phone (same Wi-Fi) as a fast second screen — if you want the snappiest, most responsive read while you drive, the phone is the place to watch it. See Setup.

Controller or wheel?

Both. It’s optimized and tested on controller (PC) today; wheels and pedals work too — it reads whatever the game broadcasts. The self-calibrating neutral means it judges the car against your inputs, however you make them.

Will it make me faster?

In a sense, yes — but the honest answer is bigger than raw lap time. The real win is that the car becomes far nicer to drive: tuned to how you actually drive, planted if you want confidence, loose if you can use it. A car you trust is a car you push — and pace follows trust. The Coach loop also tells you when the setup has given all it can, so you stop chasing the tune and start chasing tenths.

Does it work with Forza Motorsport or FH5?

Slipstream is built and calibrated for Forza Horizon 6 — its rules, its lever ranges, its physics. Forza Motorsport and Horizon 5 aren't fully supported; they broadcast similar telemetry, so some of it may work, but the reads and tune advice are tuned for FH6.

Where do my sessions live?

On your machine, in the app's data/ folder. Delete them anytime. Nothing is uploaded — see Privacy.
