Hey, quick question? Tonight after revving it hard for a short amount i noticed the engine management light came on yellow, I looked back when I stopped at my electronic memory on the boost gauge and I hit 0.9 bar? And it's a very accurate Greddy boost gauge, but how can this be as I have 0.75 set on my hks acuator, front mount with short route, decat and ct9 air filter relocate! Once I turned it off then on the light went? Before everyone says fuel cut I did not hit fuel cut and it did not judder, but it went passed the factory 0.85 somehow thanks
