USPS suck. They delay my shipping of ECU back to DHM. But once they got my ECU, it was reflushed, and was back out to me in few hours. Haven’t installed it yet, but im sure its good. Service is wxcellent as well. Highly highly recommends them

So helpful
I had my ECU flashed originally with just intake and exhaust then decided to add a cam and lightweight rear sprocket. They dialed me in with what I needed and the reflashed ECU was a small charge to include the cam and turn time was quick.

Stage 1 flash
The DHM team knows how to wake up the hidden power in the Grom. I am always impressed with their ability to reliably get their work out quickly.
