Overall Great
I will have to buy the supporting upgrades but other than that the bikes rips. ( DHM high compression piston, DHM Cam, 93 tune Chimera Intake,) and more to go overall i am satisfied. DHM is a great company to work with.

Proven flash from DHM
I’ve flashed 2 ecu’s from DHM. A 22’ Grom and 19’ Monkey. Both ran great with the flash from DHM. Definite power increase with a cam/intake/exhaust set up. The best part is the turn-around time. The Ecu’s were pretty much shipped the same day they received them.

Package never arrived and is lost it says it’s delivered, but it’s not delivered at my house. It’s saying it’s in Tampa on Kennedy.
