I can also chime in and say that I had the BMS PowerBox on my car for some time as well. The install process is much easier with two people as this is a detail oriented install and could prove better with a second person checking your moves. (Moving small wires from the ECU and remounting them on the PowerBox has to be exactly as it states or your car wont work properly)

The install for my first time took me just under 1 hour. The results were instantly noticed after installing! The car in "D" feels much more agile and better suited for the eager driver (AUTO).

Uninstalling the first time took around 35 minutes as the wires were easily placed back 1-1 without much complications.

Overall I would highly recommend this if you are looking to gain some HP from your 128. If you are strictly looking at getting rid of the throttle lag there might be better alternatives.
