BMW 230i with B48/46 JB+ question

Anyone have experiences with the 230i with B46/B48 engine with the JB+ engine mod?

is it worth it for the price, and are there any issues?

I had it for about 6 months. You'll feel the difference, it does what it says. Install is very easy. However it's not the smoothest. Hence, I sold it and went with BM3

sandrik93 How long have you had BM3? And how many miles do you have? I have been contemplating BM3 since I bought the car just hesitant because my car has 65k now and I don't want to screw up its reliability.

If you are looking for a simple to install tune at an unbeatable price , yes it's certainly with it as the gains very noticeable.

If you are looking for a more advanced tune for max power, smoother power delivery, and more features, you'll need to upgrade to a JB4

I've had a jb4 on my 19 330 for a couple years. definitely noticeable. When I had a loaner 3er while getting an oil change, you can tell it makes a difference.
