Hi guys, posting this to see if maybe someone can help me..so for some time now I’ve noticed my car hasn’t been hitting the same amount of boost it was hitting before.
My car is a 08 FSI with a K04 BorgWarner turbo and mapped with Revo “stage 3” file.
I used to spike/peak boost to about 25 psi and then hold steady around 22-23 psi but that spike in boost is gone, I can’t get to 25 anymore, my peak boost right now is 22.5 psi but it holds it there until almost redline (in 6th gear) that’s what makes me believe it might not be a leak? also it feels like boost builds steady just a little slower and less aggressive than before, it would get up to 22.5 psi and stay there as in before the needle in the boost gauge would jump really fast all the way to 25 and then slowly start to go down.
Anything you guys could suggest me?
I was doing some reading here:https://www.turbosmart.com/news/boost-spiking-explained/
It says something about the wastegate opening up too soon? Could that be it?
