I recently purchased a 2007 reg rr sport 2.7 tdv6. I intend to have it remapped to try and increase fuel economy and power. Does anyone know what results I could expect and also recommend anywhere in the UK that could do it?
He can tailor a map to your requirements - I did not want HP increase but a torque increase at around 100-110kph to assist in overtaking when towing my campervan. Unloaded my 0-100kph time decreased by nearly three seconds with the map - no noticeable decrease in fuel consumption but you do tend to use the extra zoom zoom. If you drove it like a standard TDV6 I guess you would use less fuel as the map id more efficient than standard.
The other advantage is that the map can be taken off and revert to standard in a couple of minutes and put back on when you want.
