GReddy says if you can't drive the dream at least you can get the sound effects - if you're an iPhone user. By downloading this app, you'll be able to use the accelerometers in your phone to accurately calculate throttle position and simulate how your engine is boosting (if this applies). Other fun features include an electronic boost gauge and SMi gauge where you can simulate blow-off sounds, set soft or hard settings for the Type-RZ blow-off valve to vary those 'whhpsssh' sounds or dial in boost settings for the Profec B-spec II boost controller. The app is perfect for showing your friends or significant other how car crazy you are and becomes quite addicting.
