Title: waste gates 2010-2012 sho
Post by: Vvvdannyvvv on April 26, 2019, 02:14:06 PM
2012 sho, 103k miles

at 9lbs of boost its showing 78% duty cycle

at about 16 psi ish its showing 100% duty cycle and shutting the butterfly. Car pulls good up to 100 duty cycle no issues.

I had the passenger side turbo replaced a year ago from ford. (this included the whole assembly)

is there a way to test old turbo and see if that waste gate is the issue?

Use a calibrated vacuum pump and see where it opens up.. most are completely open at 10 inhg
