Hi everybody,

Can You tell me what can cause a problem with my overboosting turbo?

I ask for 1.2bar max and turbo goes up to 1.315. SVBL is set to 2.25bar, but turbo seems to don't care about it and is boosting more than this. I also wanted to ask You about correct values of N75. I think that mine are to high.

I am thinking that maybe it's because of broken N75 valve or maybe maf sensor. What do You think guys?

The turbos on pd100 are known for boost creep at high speeds...try to cut fueling after certain rpm
