Any JB4 regrets? Issues? additional thoughts?

[. also will install draggy today before the test and will do map0/1/2 runs]

Nice, Draggy result are where the proverbially rubber meets the road.

Today me and my friend are planning to do more tests with the jb4 as last one was a bit disappointing. Will have the logs send over them and analyse.. also will install draggy today before the test and will do map0/1/2 runs

Looking forward to see how you go. The emira contacts I have all confirmed with me significant improvement in performance since the JB4. It’s not imaginary. If it doesn’t feel like a big improvement, then there’s likely something wrong with the unit and I’d be contacting Berger. I’ll be putting mine on the track in a couple of weeks with Lotus cars (our lotus dealer) to test my car around the track to see if it results in reduced lap times. By the feel of it currently. The pull out of the apex should produce a much more balanced exit.

All you folks are going to need new rear tires soon!
Looking foward to seeing quantified results in addition to impressions, as I am still weighing my options...

See my post in the jb4 section for the test results

it would be very important to ensure which is which (i4 vs v6) as I'd bet majority of people with issues are v6 folks.

v6 indeed
