Very easy to fit, 10 minutes tops. Noticed the difference straight away. Put it on the top map, massive improvement. Much quieter, smoother drive,better pickup from start, effortless overtakeing, even better economy. Makes me wish I'd gone for the next one up for more improvement. Great piece of kit.
I had looked at tuning chip boxes a year or so ago at £360 and decided to wait, I then saw Bluespark box on the Internet at £150 for my Mondeo diesel so I ordered one. Easy to fit, no problems with dashboard lights, started first time. Power up, torque up, smoother running, going round roundabouts in 3rd gear, great. At 30mph it was showing 70mpg on my trip computer.
