Another weekend #diy project - 20-30% power increase on #Honda #Grom . These are made for affordable, reliable, daily transportation - which means lots of power is “left on the table”. I already have high flow exhaust, so remaining easy power upgrades were: intake, camshaft and ECU retune. Went with Chimera short ram intake, Decha Performance HR camshaft and DHM ECU stage2 retune. Now the motor keeps pulling hard above 7k whereas before it ran out of breath.
