I've purchased a 2009 Aurion ZR6 recently and intend to convert to LPG. All installers I've spoken to have told me Vapour will see no noticeable, if any, loss of power. Some have told me Liquid injection will improve power (over petrol) and efficiency (over vapour). While others have told me vapour is all I should get because it's proven and liquid is too new?? Has anyone experienced the difference? Interested in wear and tare, power & efficiency. Also, would love to hear recommendations on installers to use. Any advice appreciated! Can't tell who's telling the right story.
