As the name implies, the DELTACHIP features up to 3 Tunes (2 programmed by rpmoutlet.com and one Stock). The Tunes are selected by the three position switch, included with each DeltaChip. The third position of the switch (the Stock Tune) actually turns the DeltaChip off - a great feature, allowing diagnostic scanners to freely 'talk' to the EEC (same as if the chip wouldn't be plugged in).
