Does xHP work together with my specific engine tune?
Yes, xHP does work together with every engine tune. The most common engine tune-Apps are:
MHD - Does have a checkbox that needs to be ticked, to ensure optimal performance, see the next question below.

MGFlasher - Does work out of the box as well.
