Sorry meant was tq 50 Motor
No worries on the typo. So, TQ HPR50 - the pin-ring motor found in bikes like the Trek Fuel EXe and your Slash+. First things first: get the TQ app on your phone and pair it via Bluetooth. That's where all the useful tuning lives.
The app lets you adjust peak power output, support characteristic, and acceleration level across each of the three assist modes (Eco, Mid, High) independently, so you can make each one meaningfully different rather than just "a bit less."
The default factory settings are conservative. Around 150% amplification is the default, which TQ designed to give the most natural feel for riders coming from unassisted bikes, but it's not the ceiling.
With all settings at max, the motor character changes slightly - you'll feel occasional small jerks in slow technical sections, though it's still manageable. Whether that trade-off is worth it depends on how hard you're riding.
Our own community agrees the defaults leave power on the table.
@Tekmotiv found the motor has
noticeably more push once you've updated to the latest firmware and customised via the app.
@levity's approach is worth noting too:
setting max wattage to 300W across all modes so you never feel that support drop when you push harder than the preset expects.
