Piggyback?
Opinions please:
Wanting to add a piggyback unit, 1 plug easy on and off for dealer visits.
Trying decide between the Dinantronics Sport Performance Tuner or the Racechip S. Cost wise both are about the same, but appears the Racechip may provide a bit more power. However, the Dinan has the ability to connect to app to adjust.
Thanks
