As i remember Tom's launched similar kind of product for Toyota cars with differenct settings as normal, sp1, sp2 and sp3 accroding to response speed. and evertime it would automaticly reset to normal when engine restart. I think sprint bootster would be more effecitve on automatic lupos, because obviously automatic ones are suffering lag when downshift and overtaking. This device seems reduce the lag by increase electronic throttle response. Has anybody tried the product yet? I'm quite interesting about it but as most people said, it's no cheap--__--
