Hi all. Had the cooper d less than a week and already snooping into tuning mods. I traded in a 238bhp TT so missing the oomph. Had to go for big mpg and the mini ticks every box. Love it to be honest but a little more poke with make it fantastic. Seen a few 'tuning boxes' but always like to research before taking the plunge. http://www.synergy-chiptuning.com/mi...el-tuning.html saw this and fancy it. Anyone any experience?
