    can you get better MPG by having the engine remapped? can a v8 chevy be remapped?
    who can do the work and at what cost?

    problem could be finding someone with the necessary software for re-writing the chevy ECU.

    you probably wont improve on MPG but will get more torque

    I have loads of torque as it is so no point in getting any more
    would like to find a way of getting a few extra miles per Ltr

    A FEW extra miles per litre :Eeek:

    you dont want much do you :Laughing:

    even a few extra miles per GALLON is a pipe dream mate, and you'll be lucky to get an extra hundred mtrs per litre.

    the expensive way to increse MPG is to run on LPG....

    i get 8mpg on gas and 10mpg on petrol but gas is half the cost of petrol so i get 16mpg

    I see a minor problem with this......

    only the 'High power, ultimate performance' option is suitable for a petrol or diesel engine....which may add a few extra BHP to the 300+BHP you already have :Doh: but fuel will suffer.

    the other two are for diesel only. :Sad:

    Theres a dead easy and FREE way of getting a few more mpg from a V8. Dont put your foot down as hard, simples :thumb::thumb:

    Anything else and your just spending money on something other than petrol. A light right foot can and will save you money :Wink:

    AAARRRRRR yes but you see the thing is, I knew it would only do 8 mpg when you floor it before I bought it and I had to ask myself...am I bothered...the answer...I bought it anyway :Rofl1::Rofl1:

    Having said that it does about 20mpg on the motorway towing a big trailer which is better mpg than my Citroen Relay van!!!

    thank you for all your input on this thread

    I drive an automatic so once it is rolling along at about 20mph i just tickle the auto cruse to chug it along,
    i get 10mpg on LPG same on petrol but that is double the price


    i suppose if i realy wanted more MPG i could remove the water tank fridge/freezer, bath room fittings along with kitchen fittings
    heavy (but comfortable front seats) 4 X 120AH batteries air con
    roof box 1x solar panel,
    may do better MPG but not as comfy as is now
    so i will leave well alone and enjoy all the comforts of home :thumb:
