Hi there,

I have a 2007 ranger thunder 2.5 TDCI and im thinking of getting it chipped or remapped. Could do with a little more torque and power but mainly want to improve the mpg. Whats the difference between chip and remap? Do you really get 40% better mpg and more power? What is the down side to this?

Thanks
Sam

Forget both and go for a tuning box, easier to fit remove and sell if/when you change your motor.
Don’t forget you should tell your insurance company about any performance upgrades.

This is a link to one company I have used and can recommend, there are more out there so you might like to shop around.

their web site has a Q&A section and they are good at customer services
