do i gas or not?

hi all would anybody know what is the best?
im running a 4.6 range rover p38, im thinking of gassing it but dont know if having the ecu mapping done would get the same result at half the price? has anybody had this done?

I don't understand the question but the italic font and highlighted p38 are very impressive for a first post.

The question doesn't make any sense - having the car put onto LPG is completely different to having the ECU remapped. Not really sure what you're getting at here matey

id gas it all the way although the initial layout is a lot more to gas it in roughly 4 years time the money you save on fuel will be twice as much as you spent on the conversion plus if its done by a registered gas instalation garage they usualy give 3 years warranty and if you decide to sell the vehicle again theres no stopping you getting the gas system removed by the garage and put in the new one usualy at the £400 mark
whereas the remapping can cause allsorts of faults if not done properly
