Renault Laguna III 2L TDI
I was averaging 45mpg but with this fitted and now up to setting 8 I'm seeing an average of 67mpg. That's an almost 40% increase! I am extremely impressed and wish I had bought this earlier.

Finding the connector not quite as easy as video showed on other Audis, but eventually found the right one. However, what a difference! Flat spot on acceleration now gone and so much quicker! Great value and highly recommended!

A great difference
I recently bought a diesel chip initially to improve my fuel consumption, very easy to fit and then, trialling the settings, i started with the standard setting of no. 3 than advanced to No. 4.

Simply plug and play technology. 2.0 Jeep Renegade Multijet 4x4. Fitted in under 2 minutes I now average 53.6 mpg on motorway and 45mpg towing my boat. People need to re-evaluate their reasons for not having fitted one. Wish I had this sooner.

I recently fitted a chip to my 2014 Ford Galaxy and it has transformed the performance. Smoother, more responsive and the average fuel figure is slowly going up. Highly recommended !!

Fiited to 5 yr old Vauxhall Mokka 1.7 ... not for speed but needed a little help. The fitting would have taken 2 minutes except I needed some smaller hands :-) Just set it level 4 & impressed
