Worth every cent! I’m very impressed with the performance improvement.
Dhm reflash and tb cam woke up the Grom
The bike pull way harder on high rpm. Fast shipping smooth transaction. Thank you guys
Wakes up the top end like it needed! Makes the motor breath like it should! Love the upgrade and power increase. Sent out my ecu on Monday at 6pm. Received cam and tune on Saturday morning. Great job DHM!
Quick shipping, easy install, cam was really nice quality. Broke it in quick and man this thing is a blast. Tunes on point, pulls hard thru the band. Can’t wait to race my friends! ( I didn’t tell them I got an upgrade ) will be doing future biz with DHM
**Cams are in stock and shipping!
***If you already own a DCR or TB camshaft you can still purchase our Reflash for those mods here: https://www.dhmotoring.com/products/stage1reflash
If your Grom already has an intake and exhaust, this is the next step!
We've created a camshaft package that allows you to add a TB camshaft and our DHM Reflash to your bike. This will add as much as 2-3hp and will also increase your rev limit to 10,000 rpm, while also correcting the fuel and timing tables in your ecu. Your Grom will experience much stronger high RPM power, as well as the ability to pull to higher RPM before shifting. After tons of dyno and street testing, we feel this it the best bang for buck upgrade available!
Corrected Air/Fuel ratio for your exact modifications
Increased ignition timing for throttle response and HP
13+ HP depending on your intake and exhaust setup
10,000rpm rev limiter
Normal cold start functions (no bad idle issues when cold)
