Piggybacks are much more prone to these types of issues but certainly do what they advertise in a roundabout type of way. I'm very interested in tuning a meth kit using the stock DME only. I think that the same gains can be achieved. One benefit of the piggybacks however are aftermarket features which usually can not be implemented with the stock DME only.
What i like about the proceed is if for some reason meth flow stops, the proceed will fall back to the stock map. If you tune a stock ecu for meth, say you run out of meth, now you are tuned too lean/ too much timing. Also, there really isnt a way to control how and when the meth starts to flow and how much of it. I drove for about 6 months without any issues at all! Then again, i havent drove my car is 6 months either
