JB4 Beta Installed and Reviewed

Hey everyone, I just installed the new JB4 tuner from Burger Motorsports last night. Story goes I ordered at jb3 pin out around Xmas and for some reason it didn’t work. Terry was very helpful in emailing me back and assisting with wiring issues. In the end we still could not get the jb3 to work so Terry set me a JB4 and it has been amazing ever since.

Just like the Jb3 my e90 is now 10x the car it used to be. I am running map2 with 93 octane, the map is smooth and responsive. The endless amount of torque from 3500rpm – 6500rpm will throw you back in your seat and leave you with a smile that doesn’t come off.

The new steering wheel controls are very easy to use, follow the map guide that Terry has posted on the website and setting shift lights and gauge hijacking is a breeze.

I just wanted to say thank you again to terry for all of your help, I will be purchasing more from your company in the near future.

The jb4 is no lie. Boost really comes quick and does appear a lot smoother on the datalogs.
