GReddy

This is by far the worst 99 cents I have EVER spent. Never buy this.

Same exact app as Iboost with greddy advertisements and costs 2x as much. Made by same company. Give your money to the real developer.

This is very fun to have, gonna play it on my friends car stereos haha!

Pretty cool app! Fun to play with in the car!  Hope to see some future updates.

Thank you everyone at GReddy for making this app I have been buying GReddy parts for years so I no they put a lot of thought in to it just like every thing that they sell I love the app and hope u guys think of more apps like plugging our iPhones to our cars or something thanks again for all your herd work

me gusto pero le faltan mas opcciones y sonidos

Fair warning do not get this app it's is horrible it never goes in sync also the BOV sounds horrible and the turbo sounds like a jet.

Though I have a real blowoff valve and turbo I don't need this app but it would be great to add music (your iPod songs) for the cars I use that aren't aftermarket/tuned. Or for people who don't have the real deal, just an idea
