Has anyone tried the RaceChip GTS?
I have owned my X2 for a little over a week so excuse my lack of knowledge. I have been doing a fair amount of research with finding wheels and tires and getting rid of the chrome and aluminum accents. I have done a small amount of tuning research and a little into upgrading the audio. There seems to be a decent selection of plug and play (in-line tuners) Racechip, 3D designs, JB4 etc. Has anyone purchased any of these?
