Sounds awesome, I've been itching to pull the trigger on the JB for a while now. Maybe I'll have to just give it a go.

How is power delivery with the JB? Everything smooth? Any crazy peaks or anything in the curve?

Ive got a jb3 n55 stage 1 and USB cable for sale - works perfectly on the x3/x5/x6. PM me if interested, asking $320 shipped.

Anyone do the BMW factory ppk to maintain warranty? Dealer said they have no idea how to do if it isn't an orderable accessory on the build sheet.

My dealer offered the option to me but suggest that I should wait for potential options from more reliable tuners because the OEM PP is ridiculously overpriced.

I wasn't aware that the performance upgrade was available for the X3 at the dealer... does anyone know if this upgrade is available and if so, has anyone evaluated the performance?

I didn't think it was available for the F25...

I'm a new member so I can't pm you right away. I will take the jb upgrade from you if possible

Hey what is your opinion on the jb N55 stage one? Is the difference worth it? I assume before service you remove it ?
