Hi,
I am currently looking at plug in switchable remaps for my A4(B7) 2.0TDI 140 so i can switch it off and remap it myself- in case of the system being flashed during services etc. Has anyone out their had one put in, or has anyone had either BLUEFIN, ST3 or can anyone comment on the EMotion plug in system from Celtic tuning?????

Thanks
Kev
