Would you personally use one of these? Am I right in assuming they are not very good for getting 100% out of your engine? I guess they have their advantages. However, Dream science have many different maps within the unit. Economy, Performance, Race, Race Plus and so on. Am I wrong to assume a remap will give you all the above in one map?
Thanks, Benni.
