Tired Turbo?, need suggestions

[suprbuick7]

108,000 miles original turbo. Recently I've only been able to boost 10lbs.@WOT. stock non adj wastegate. My Plans are @ low 11's. With 50 lb injectors

Go for the TA-49. Good on the street and can perform at the track when all is set up properly! Get an adjustable waste gate rod. You can make one for a couple bucks with your stocker.

not really a turbo based question, but maybe more of a problem getting the exhaust to the turbo?

pull the MAF pipe off to the turbo and see if the turbo is still tight-
if so, then check for excessive exhaust leaks or a bound up wastegate puck- if the car spools up slow and runs low boost, maybe the wastegate is not seated properly hence the low boost-


pressure is required to the wastegate to lower boost, so if the hoses are bad, you will get more boost-

also- taking a hose from the silver compressor housing to the wastegate will get you 12 psi and no creep-

check the above and see what you get-
