We don’t just sell you the device — we connect you to our tuning network for precise, dyno-tested calibrations built for real-world drivability and performance. Whether you’re on the track, trail, or highway, the RTD4 gives you professional-grade tuning power in your pocket.
Customers will download the app, make an account, and connect to their interface via Bluetooth, they need to enter the Blessed Performance invite code. Once they are accepted to the our network, they can retrieve a stock read file from their vehicle and send it to Blessed Performance. After they receive a custom tune file, they can flash it back to their vehicle in just minutes and start data logging on their phone.
If DTCs or fault codes are present, they can clear or forward them to the Blessed Performance. This process eliminates the need to have a bulky computer on hand. The ability for a customer to do all of this on their phone is highly convenient!
