Works good

Seems to be working. I did order the aracer though just because I have plans to go bigger in the future but if you are going to stop at 149cc then IMO a flash will be good enough. Really like DHM products.

Fantastic service

I needed some help and David contacted me when I asked a question in a Grom group. He was able to help, flash my ECU and send it back extremely quickly. I'm extremely happy with the flash and will be back to buy more upgrades!

Grom tune

I bought a Grom and was given questionable at best information as to what tune it had. After looking through what I was given I found out it was tuned by DHM. I contacted them and was replied to very quickly and had all my questions answered, even the stupid ones. After some back and forth I decided to send my ECU in to see what tune was on it and found out it was not correct for what mods were done. He quickly corrected it and sent it back which completely transformed how the bike ran and I could not be any happier. I will definitely be returning to DHM for all of my Grom needs.

Custom Stage 2 Tune

Sent him all the relevant info for my setup, he made me a tune that ran a perfect 12.8:1 AFR at wide open throttle. Showing 12.6 HP at the wheel on the dyno, im very happy

Fast service and shipping

Very fast service, great communication and shipping speed. Gave my grom more torque and power for uphills with the added parts and tune. I'm definitely returning if I ever decide to upgrade the cam.
