I Purchased the standard size high compression piston and later had a stage 3 ecu remap this has totally transformed the ride of the bike I highly recommend this upgrade it is amazing buy buy buy 👍👍👍
Everything is spot on! The cam was easy to install and the ECU update is perfect. Cruzing 65mph is much easier. Thanks DHM!
So I have done many upgrades to my 2020 Honda Grom. The intake, the exhaust, the billet velocity stack, the tail tidy, the new seat, the, but the real upgrade was this one with DH motoring. I purchased and installed the TB cam and the stage 2 flash. I also did the high flow oil pump. Tremendous increase in power even during the break in. If you’re considering any upgrade that you would like to actually feel this is the one.
Big upgrade from stage 1, can really feel de power difference with tb cam and stage 2 flash, everything works really well!
I already had a flashed ECU. Thought I would add a better Air Intake and it wouldn't change the A/F much since it was already modded. Wrong! A/F went way up. As soon as I re-installed the new ECU the A/F was back down where it should be. Terrific service. Answered all my questions.
