JB4

Has anyone done the JB4 upgrade on the 2.0t. Im curious as to what the gains are and if its worth it on the 2.0. Also, would this void the warranty?

We've sold tons for the 2L, works great!

Any modification can result in warranty denial if they find it and it likely caused your problem. The JB4 is designed to be safe and effective, and removes without a trace when needed for diagnostics.

Do you know what the specs are after install as far as increases to torque and horsepower?

I have a 2L and JB4. I would highly recommend it. I have not had my car on a dyno so any estimate on power or torque gains would be purely speculation. But I can definitely tell a difference.

I would also recommend the BMS Pedal Tuner to get rid of the AWFUL turbo lag on the stock 2L. Doesn’t add any HP or torque but makes the gas pedal much more sensitive, and the car much more fun to drive.

An intake will add some HP and torque, but just be prepared for much louder turbo noise. I don’t mind it at all, but for some, it is too much.

Happy modding!

I haven't done any 2L dynos personally but I think customers have. I know at least one is using the JB4 to power himself to 13.x 1/4 mile times.
