New here - Question about EK1 BEF

[CarterVG24]

Hey guys, finally made an account cause I have some questions before I dive into my next mods.
Trying to do some research while im deployed for what I can do when I get home.
-Instead of getting a Lozic ECU and TCU, ive been reading about getting a EK1 BEF since I already have a jb4, how are the results, and how do the bubbles sound and for those who have it is it worth it?

Thanks

I just got the KJT E30 ECU with moderate burbles + BMS TCU bef tune done and it is AMAZING! Cmbuildz helped me set it up. Took some videos of it after:

Here is how it sounds driving it:

It is a perfect amount and is barely noticeable in comfort mode. It's more when you are in sport/custom mode and especially if you are manual shifting which is the icing on the cake with the bms tcu. I will say the ek1 device was an absolute pain to work with since we were having issues with files not being shown on the device. Luckily thanks to cmbuildz he figured it out.

It's a day and night difference from jb4 alone. Absolutely worth it! The power difference is huge! Smoother power delivery, less drone in the 2-3k rpm, softer cold starts and much better throttle response. The exhaust even sounds more refined in a way and you can hear the cold start turbo whisle nicely. You can even hear the whisle almost just idling. The intakes and BOV are also louder as well. Boost comes on sooner without that dead throttle feel in the lower rpms. Kinda wish I did this earlier!
