low boost w/ chip and intake
hi guys brand new on here and want to run a couple questions by people in the know. First will discribe what i'm working with: 2000 F250 7.3 160k miles, TS 6 position chip, AFE Stage 2 intake with ProGaurd, Edge CTS. About to get 5in turbo back MBRP exhaust with muffler delete.
That out of the way...when in stock position boost is reading max 10psi WOT. Wastegate duty cycle on idle reads 98.8% and lowest it gets is 68% WOT.
When in 50HP position constantly reads 98.8% wastegate, max again 10psi
When in 140HP same deal but wastegate does fall to 68% like stock.
What im asking is what could be going on with this. Could turbo be shot? Ive sprayed soapy water on uptake boots and no bubbles any other way to check? Ive heard donuts could be bad but havent checked.
