QUOTE=bren335i;6236982]Simple, doesn't matter what engine because its not tuning anything.
It biases a fuel signal and leans the fuel out a bit on the stock map, no timing control, no ecu control. And then amplifies/multiplies the stock drive by wire signal as much as possible to make you think you are going fast. Which is the incorrect way of doing it, as all the torque targets and DBW factory mapping is less then desirable to start with. However, it's simple and effective to your market - hence why it works.
a sprint booster and an ebay resistor .99 mod.

Actually, a sprintbooster and the BMS powerbox are two different things. A srpintbooster simply enhances your throttle response, you get no hp nor torque gains whatsoever (its also on their website). In the other hand the BMS not only does it enhance the throttle response, but it also gives some extra hp and torque gains, its also installed on the ECU. The sprintbooster is a simple PnP cables that goes on your pedal. Hope this helps.
Sprintbooster pricing nowadays are close to the $175-$200 range (used on forums)
BMS PBox are close to $200+.
