:Dtuning box or remap for my cupra fr tdi? which is the best to get, i see ther is a big debat over which is the safest......helllpppp please
 
remap is best if money is no object

Tuning boxes seem to just fool the ecu into increasing fueling, give good results for the money as can be as little as 60quid but tend to give smokey results when you boot it, Really just the modern day equivilant to winding up an old mechanical diesel pump.
