I have the Zoom Loop exhaust, chimera intake, and this kit. This kit made my 22 Grom come alive. Turn around time for my ECU flash was very impressive. Definitely want to have an actual piston ring file for the install. Very happy with my purchase. Thank you DHM!
The DH Motoring Stage 3 Package includes the following:
Combined with your aftermarket intake and exhaust, this is the most you can get out of your Grom without doing any head work. After dyno testing we were repeatedly seeing 13hp at the wheels (SAE) run after run! The Stage 3 package makes more power than a stock Grom at every RPM and double the horsepower at 9000+ rpm! 91 octane fuel is absolutely required. Any fuel with a lower octane rating may result in engine damage!
You can choose to receive a preflashed ECU instead of sending yours in ($95 extra), or you can send yours in to be flashed.
