I hadn't heard of the BM3...looks promising after a quick look and thanks for the heads up on the shop in Chantilly. I work from home in Winchester, but occasionally go into an office in Chantilly. I'll have to stop by there next time.

The JB4 from BMS is tempting as they are routinely available on the forums and have a good bang for buck. I think if I were to plan anything serious, I would likely go with a Dinan type package as their tuning seems more comprehensive and would work with their supporting parts as a more cohesive solution. (That's just from inital research, no deep dives yet)

Isn't the JB4 plug and play module completely removable though? Or would there be traces of the impacted tune?

For now, I'm still in the "should I get a warranty" stage though.   I realllllly like it and don't want to end up hating it over a repair that costs way more than it should.
