Anyone using a jb4 on there g30? Do people still use them ?

LOL yes they are still the best selling piggyback. The B58 is the most popular JB4 we offer, we get them in batches regularly.

I have a 540i x-Drive G31 LCi 2021 would a JB4 work on that? if so any downsides / CEL issues etc?
Thanks

Works on your car without any issues.
As long as the item is installed correctly, no CEL or downside

Thanks Mike, Good to know, I'll read up on this & think on it.

Do you also know if the Remus axle back is suitable for my car (has the MHT)?

Many thanks

it's the best-sounding exhaust at this time in my opinion, but it's almost never in stock. The Dinan is the next best option

..and they both fit the B58C LCi with the MHT?

Thanks

I've heard of people running them on top of a tune. Is it a viable solution?
Does one need a custom tune or can it be done with a canned ots one?

You can't run the JB4 on top of another piggyback. you would need to run it on top of a flash tune, but doing so does not make sense because you are getting the jb4 so you do not go through the hassle of sending your ECU to Finland. If you sending it anyway, you might as well just go with bootmod3 instead.

Unless you are running big project cars with methanol injection or Port injection, running a piggyback on top of a flash tune is not worth it

I'm already running a bm3 tune, I was referrring to people stacking the jb4 on top of a flash tune for more boost but wasnt sure if they were running a custom tune or ots.

i see, i would not recommend doing that. If you want more power, get a custom map for your bootmod3. We offer custom maps by Jordan tuning
