I think out of all the tunes then, this might be the best choice for the price then. It's not like the tuner detection codes is going to matter at this point, considering all other systems involve something similar (piggyback), or a ECU flash (super obvious).
Looking at the price, this unit may eventually sell enough for a Stage II (around ~250 units), which might actually have multiple maps ... seems like the more viable option in the long-run. Best part is, it's essentially a plug and play, we don't even have to splice wires.
