any actual dyno or dragy results for JB4?

Has anyone actually put the JB4 to the test? Would love to see some real world results with either a dyno or dragy.

I saw the claims they make on the website but I’m skeptical.

There is an old thread BMS made with drag strip results. I have been using a JB4 for over 2 years. Now I use a flash tune and the JB4 adds more boost when the meth is flowing.

Why are you skeptical, it adds more boost which increase power.

On average 1 PSI of boost adds 15 whp and 20 wtq

Butt dyno says it 100% works. Need to connect the EWG cables and run Map 2, but after that you'll never want to unplug it again.
