We tested the Blitz Throttle Controller today, and it definitely works. Install is a snap, literally. No splicing etc, just unplug your accelerator pedal and plug this in. We definitely give this product from Blitz the thumbs up.

In the most aggressive mode you notice it immediately, even backing out of a parking spot (don't worry Reverse Cancel Cable available as an added option, which disables the function while in reverse). The engine is snappier with revs jumping up faster than before, similar to the effect you get with a lightweight flywheel. While this device adds no power and simply opens the throttle quicker (seen in diagram below), it does make the driving experience more fun.

This controller has plug and play applications for numerous modern drive by wire cars such as the Nissan 350Z, Infiniti G35 and G37, Scion tc, Civic Si, Subaru WRX and Sti, Mitsubishi Evo X, Mazda RX-8, as well as many others. For a complete product description from the manufacturer click here.
