is tuning for fuel worth it?

[calais_304]

hi all,

just thinking about going and getting my car tuned to run on 98RON, what i really want to know is, is it worth it? do you notice any differance in econemy? do you notice any differance in power? does the car run smoother?

what are your thoughts on this?

cheers all

on a 5.0 litre that is stock i wouldnt waste your time or money, it wont give you any real gains.

no worrie then, what about a 195 as they had some stuff put in them (wouldn't know what but i know one is a roller cam or rocker?) and i've also done cold air and full exhaust, would that cause it to give a decent gain or do i have to sorta go full out with mods before it will show any affect?

cheers

dont know if its a valid point but my vn v6 is stock besides shift kit bigger diff gears cold air and exhaust it loves the ethanol fuel 95 or 98 oct but on reg unleaded it goes sluggy but i always make a point to do 2 tank of eth 1 tank of reg to burn all the sugars off and my mech said its never looked cleaner since i started this practice
