Hi everyone, i got another clio DCI now ( 172 has gone) and i want to improve the mpg. I was looking in to the tuning boxes, and woundered if anyone had one on here or had any knowledge on them?? Do they improve the MPG by a lot on the DCI? I had one on my Xsara HDI and it did also any brands of tuning boxes recomended?
Thanks
Jon
