I am looking at a DINANTRONICS or ChipWerke piggyback tunes. Anyone in here have experience with either. I realize that a full flash would be better, but I cannot send my ecu away for the amount of time that would be required.

I noticed that Dinan flash is only modifying the data to one sensor vs multiple on the ChipWerke. This could be better or worst depending on how it’s applied.

Input?
