DIY: V6 Burger Motorsports JB4 Installation

[Hugh888]

Can you post/show a before/after JB4 map done by a 3rd party that clearly gives the before/after?

I think people are trying to do it because there hasn't been much customer verified data.

I say this as a very happy jb4 owner.

David, I agree with you and I am a happy jb4 owner with eventuri cái and milltek valve control and exhaust system.

I like to know how much hp to the wheel I have lol
