At first, it’ll seem weird but nothing to worry about if you’re doing this for the first time. But what I mean by vtec is the way the grom PULLS as soon as u hit 7k, I’m talking a sudden pull. I’d definitely recommend a cam gear so u can even it out but if she pulls hard with a eBay exhaust, chimera intake, cam, 60% springs/plate,koso pump,iridium plug, and a 39T sprocket on my 2023. Set the valves to what dhm recommends, u should hear ZERO ticking don’t let people fool u with their misinformation. 100% would go dhm over any other brand
