Had a similar experience. Seelye had mine for 5k over and lost so many sales that I beat them down over a week with some games and other dealers. Turns out when another dealer has one at MSRP they will want to move a unit.
They did get me back by jacking up my rate and pocketing the difference...
It's just a rebranded RaceChip. Extremely low resale when you realize how junk these systems are. If you want a proper piggyback a JB4 is the way to go.
I bullied my local dealer into dropping back to sticker due to them missing about 5 sales on it in the past month. If you make a compelling arguement it can happen. Dealers are hungry to move inventory.
