    300 HPDI Mods

    Just purchased a 22 Activator with a 300 HPDI Yam on it from the Doc. Some of you may have put more power & or reliability into keeping these engines alive and healthy. I'm all ears for your suggestions and experience with these engines. TIA for your replies.


    Forgot to add that I know about Hydro-Tech and did do a search on here about the HPDI.
