Default slow boost and maxes out - 05-23-2021, 05:53 PM

Ok so I have had boost leaks wondering if it is the same again. but it does not seem the same.

I recently replaced the water pump and it was dead from the get go. On the first drive it felt great but then wanted to overheat. parked it.

I replaced it...Again I did end up kinking the wastegate vacuum line witch I fixed and yet the boost builds slowly and then maxes out at just over 12.

Any ideas?

Your FF and wastegate duty cycle are completely maxed out.

It's likely a boost leak or other hardware issue.
