DHM Reflash and TB Cam Package (Stage 3) 2014-2021 Honda Grom

**Podium and DHM are currently out of stock on HC pistons. Waiting on more from overseas, you can purchase, but it will be a preorder till they arrive** 

The DH Motoring Stage 3 Package includes the following:

• DHM ECU Flash
• DHM High Compression Stock Bore Piston
• TB or Decha Camshaft
• NGK CR9E Spark plug with spacer

Combined with your aftermarket intake and exhaust, this is the most you can get out of your Grom without doing any head work. After dyno testing we were repeatedly seeing 13.5hp at the wheels (SAE) run after run! The Stage 3 package makes more power than a stock Grom at every RPM and double the horsepower at 9000+ rpm! 91 octane fuel is absolutely required. Any fuel with a lower octane rating may result in engine damage!

An oil cooler and extra crankcase vents are recommended for this kit. 

We offer the following crankcase vent systems:
