iBoost makes your car sound like it has a turbo!

Featuring authentic sounds recorded from over 16 real turbo cars iBoost will amaze you with how realistic it sounds as you drive. Make your car sound like a Skyline, Supra, WRX, Evo and much more - even an oldschool Group B rally car!

iBoost knows when you back off the throttle lightly or when you shift hard while accelerating. Compressor surge, wastegate, blow off - its all there!

Choose from 8 different styles of boost gauge that work just like the real thing as you drive! At night each gauge lights up with awesome illumination mode effects.

“The app pops up on your screen looking just like a real gauge... and in a vehicle performs almost exactly like an actual boost gauge. It’s pretty cool!!” - Fast Lane Daily

"It's an incredibly well designed app and a lot of fun to play with! An must-have for any car fan." - HKS Japan

We highly recommend playing iBoost through your car's stereo and confusing people as you drive past!

I was surprised

I was actually very surprised. I mean for just putting it on a window mount and using your phones gyro, it's pretty great. There's like half a second of lag between taking your foot off the gas and the blow off, but i wouldn't really expect any better given the way it works. The only thing I don't like is the volume. I like to listen to music from my phone, and you can barely hear it over the music. You can't even adjust the blow off volume, just the compression, which you can't hear at all even at max volume. If they fixed that it would be perfect.

Best Value Mod

This is the best value you're gonna find for a car mod. Gave my Honda Civic 69 more horsepower. And you can always get yours and your passengers phones running it together. It just stacks! Once I had 4 phones going, and I was pushing 400 horsepower in my Civic! And for only $4 total!!

So much fun

I love this app. It sounds just like the blow off valve on my car. So much fun.
