right seams like no one has had any experience with these, they turned up by post yesterday had to remove the ecu and install the new chips, took her for a spin and noticed straight away a lot more toque in the lower rev range thats good but aint going to help the fuel consumption so took it for a bit of a drive down the motorway and hey 24mpg showing on the trip computer and rising never had it goe above 20 mpg, took it round town and hey 17mpg used to get about 12, so abit expensive but its still got to learn apparently over the next couple of hundred miles will update when ive done a few more miles.
