What's New in Powerband Precision
1.15
August 18, 2026
• A/B Compare (NEW): Pick a circuit — Idle, Low-Speed, or High-Speed — and instantly flip between the Rich and Lean sound so you can hear the difference back-to-back and train your ear. Each side shows exactly what to listen for. • Dyno Charts (NEW): Attach a tuned dyno chart photo to any engine in the Engines tab and view it full-screen with pinch-to-zoom. Build your dyno library over time. • More Engines: Added 17 new factory baselines — Alpha Pro .28, FX G501 DLC .21 5-Port GT, the full GiMar lineup (Saturn, Mars, Venus, Neptune, Blade, Strike & more), O.S. Speed R21 GT, and the Novarossi/GiMar 353 Race .12. • New Diagnostic: "Bogs then regains power on the straight" — covers 2-speed, one-way bearing, and belt/pulley issues. • Playback fixes: Resolved clips not playing on some Android devices and made audio streaming more reliable across the sound library. Keep those needles dialed in — thanks for using Powerband Precision!
