Hi all,

I currently using a FP Red, APEXi AVCR Boost Controller and ECU Flash.

I was using the stock Ralliart ECU and doing some logging to try get some tuning done on the car.

I noticed when i boost , boost pressure maintains at 1.3 bar on the "OFF" setting which is about correct. I was told mine was the upgraded spring in the actuator...

Any way the strange part is once i lifted off the throttle, My Boost Spiked to 1.9 bar or to be exact 1.87bar! But while pulling Boost Remains stable...

Any idea what happened?
