10/10 would recommend to anyone with a Honda Grom. I purchased the stealth intake and flash tuned ECU from DHM for my wife’s 2025 Honda Grom and couldn’t be happier with the performance upgrade we got out of it. We waited till we put about 2200 miles on a stock everything before doing the upgrades. Bone stock with no power upgrades or body modifications, originally we could get it to hit 71 mph max going down hill and 56 on a flat straight road, after doing the power upgrades as well as some body mods like a 12 bar that added to its weight, the Grom now has the ability to do 83 MPH downhill and 74 MPH on a flat straight. 100% satisfaction from this customer and can guarantee I will be buying from here again.
