Myer had 30% nitrous loaded on the big kit.
Mid-session, he decided to push it further.
Grabbed his phone,
connected to the Haltech over Bluetooth,
and bumped the tune to 40%.
No laptop.
No trip back to the shop.
Just his phone.
2.4 seconds later,
it was running at the new setting.
That's the kind of control Bluetooth tuning gives you.
