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.

Satisfied 2 time flash customer

It is my second time dealing with DHMotoring and it is still as great of a experience as the first time.

Got my ecu reflashed for my new mods and the bike run perfect. I have added exhaust and the TB cam to the stage 1 flash and airbox mod. The Grom as turn into a mean little machine!

More Power!

I can now continue to gain speed up hill into the wind without drafting. I wish there was a quieter solution for the Chimera Short Ram intake.

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.
