Apexi Avcr Boost Controller - Not Holding Boost

[HOOAH]

Hi all,

I have an Apexi AVCR for r33 gtr. The turbos will hit 1.2bar and then drop to 1bar according to the boost controller.

I'm not sure what I am doing wrong, here are the settings from top of my head -

Boost: 1.20 bar

Duty: 55%

F/B: X for all gears (I use to have 1st: 7 2nd:6 3rd: 5 4th:4 5th: 4, but I found having X makes the boost hit harder)

Learn Gear: 0 for all gears

Start Duty: 0 for all gears

Thanks in advance

I had this problem also. I started playing around with the duty cycle with rpm helped out a lot.
