The best there is

I was previously running Stage 1 on my Grom, but I decided to make the jump to Stage 2. I sent in my ECU for an update and also purchased the S1 Camshaft Gen 2. My bike rips now! David is fast and helpful if you have questions.

She's awake now!

It's crazy to think that tuning an ECU could make such a difference but boy does it ever!! DHM is my go to for most all of my Grom needs/wants!

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!
