It is highly recommended that tuning should be performed by experts. However I have experimented with adjusting "tuning strengths" of any given map. I will publish the range of "tuning strengths" that works for me. For those that had the TMC boost module, it's similar to turning the 9 position switch that provided 4% tuning strength power increments.
A good feature of the UniChip is that the OEM PCM does have some built in safeguards which may trigger engine check faults to protect your engine. However, one should use caution.
There will be a good number of maps to choose from. The rule of thumb, there is no need to personally tune maps. All that I am saying is that the maps are capable of fine tuning with someone that is knowledgeable in this area without worrying about if the map is locked.
