Advance engine timing

[jassi_hayre]

Guys (inc Gals)

 

If you convert a car to LPG (on an NA), would you then be able to advance the engine timing to gain more power? (seeing as lpg is 110 RON).

 

Would this be worthwhile? i.e. likely cost vs likely performance increase?

 

You'd have to use RON booster in the petrol when not on LPG. Any good products out there to this?

 

Thanks
