I raced some bikes last night, went 120, it was fun and there was no one on the road. BUt my car just stoped boosting like it should, it just boosted to 10psi all the time, in any gear, i couldnt understand. When i came to a toll plaza, i turned the car off and back on, and i started boosting 25 again. Anyone know why?? Why 10psi?

 

sounds like limp mode

 

Well its never happened before, but i havent gone that fast with the ko4 yet, i plan on getting a race n75, will that help prevent problems like this? Or

 

Your car went into limp mode due to over boost. I don't think that the N75 race valve will solve the problem as this delays opening the wastegate and raises boost even more.
