Today marks 2 years with the 4BW 25k miles and many more to go

You need a bidirectional scan tool (or a dealer/shop) to perform an exhaust valve re-learn procedure. Otherwise, you will (likely) experience a CEL. I ordered a launch creader elite, sounds like that tool should do the trick based on the experiences shared in other posts with the 5BW Corsa kit...

Kit should be shipping this week, everything is apparently finalized. I am excited to see the decibel readings before and after. I may even pick up a better mic

Lots of great info on this thread-- My dealer cold called after some routine maintenance with an offer of $44k on my '22 4BW (A10) during the mid summer (MSRP was $71k in 9/2022). 3rd party offers and for sale ads on stripper spec 4BWs w/ ~20K miles were listed in the $55-60k range. Higher...

They look 100% identical to me, but I have not purchased either, just speculation

CF button: https://savagecadillac.com/products/cadillac-ct4-ct5-blackwing-real-carbon-fiber-start-stop-button-cover?_pos=3&_sid=407240623&_ss=r there are also rings for the surround and the button itself in several colors available from paragon performance (plus an aluminum button option)...

what did you trade it in for?

agreed, I have a feeling it will sound completely different in person. some clips are from a phone and others have an edited/muffled sound. (the early teaser clips sound the best by far) I would like to make a comparison video when I do my install, including decibel readings as well as a...

Yes to the holding pattern and the Corsa 5BW system sounding great. They developed/produced that 5BW kit very quickly. ---------------------------- @obeykube I found the link to CPD's shop and shared a DM of what he has in the works right now (the one with black tips). This kit looks like...

took 'em long enough LOL

on the topic of these rear middle seat belts I went to fold my seats down, so I pressed my key into the middle seat belt release that makes it a 3-point harness. The thing popped out just fine but the belt will not retract all the way up to the trunk where the mechanism is. What do I do to...

Welcome to the forums all the way from the USA :beer

how?

Chased down and resolved the rattle coming from near the sub and under the child seatbelt plate. Used some foam and electrical tape wrapped around a toothpick to stuff the small gaps that were making all that noise. Now I can enjoy music at all volumes.

^^ rear - I have used the cradle brace area where the orange arrow points to with no issues so far - lift from pinch weld then lower onto the structural brace -------------------------------------------------------------------- front - put some duct tape down so you don't scratch the surface...

Send the pics!!!!

I can't make it this time around but sounds like a ton of fun

@XTRMLN Thank you for your insights. I have the green filters installed as well and an exhaust kit on pre-order from crest. Next steps after that are a ported TB, colder plugs, and eventually some resonated downpipes. I am leaning towards a dedicated unlock & tune, although the ability...

If you were to go back in time and do your tuning process all over again, would you still start with the JB4 module or go straight for the HP tuners unlock & tune? I enjoy the concept of a removable JB4, but worry about reliability.
