Why a Tach Like This Matters
Your engine makes peak power in a specific RPM range. Miss it, and you’re leaving performance on the table. Overshoot it, and you’re just abusing your valvetrain for no reason.
This tach helps you:
- Hit consistent shift points
- Maximize acceleration
- Protect your engine from over-revving
Basically… faster and smarter.

Pro Tip (Free Performance Gain… Kind Of)
Set your shift light slightly before peak power drop-off, not at redline.
Redline ≠ optimal shift point. That’s just where the engine says “please stop.”
