Cam and Flash Tune

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

Really woke up the Grom!

It was super easy to install and only took about 20-30 min. Couldn't be happier with the added power and higher top speed. Customer service was also great. Definitely recommend to any Grom owner.

Just do it

Had intake,exhaust and current tune from dhm. Added cam and reflash . Actually pulls past 7000rpm. You guys kill it.
Thanks again!


Bought the stage 2 with chimera intake and it changed the bike completely! Installed intake cam and ecu in under 2 hours. I am mechanically inclined but have never worked on a bike before but this was super easy and straight forward. Absolutely love it. I’m going to enjoy this for a bit then go for the high comp piston!

Great service!

Quick response to questions, amazing service and fast delivery. Night and day difference in top end performance on the 18 grom. Definitely do business again and recommend 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)

You have two purchase options for delivery. Once you've completed the purchase, we will email you with instructions on sending your ECU in to be reflashed. You can also choose to purchase a core ecu, we will send you a flashed ecu and you can return your original one and receive a $50 credit or keep it as a back up.
