Do all the tricks in getting more BHP from a petrol engine i.e. porting, raising the compression ratio etc etc apply to an engine running on LPG? Can you buy another 'chip' more suited to LPG? Any info greatly received, any web sites that can help? Does doing this type of work negate the benefits of LPG!......... So lots of questions, please let me know.
