trubo problems or help

i have an 00 ford f 250 PSD 7.3 with a 6 speed mauanl tranny. I have 4" exshaust with banks brake. I have super chips installed with high perfromance. I also installed banks quick trubo assembly. My problem is when i frist installed the quick trubo i was getting boost up to 24 psi now i am lucky is i can hit 20 more like 16 to 18. I do have exhasut temp gauge installed and i very seldom let it get over 900 degrees because i have inststalles post trubo

Thanks rob

That doesn't help much because it is post turbo temps that you are taking. I HIGHLY recommend that you mount that probe pre-turbo.

Now, for your issues, it sounds like you have a boost and/or exhaust leak. Start checking your CAC boots for leaks, cracks, or loose clamps. Also look at the exhaust manifold and up-pipes for any signs of leaks.

You can remove all 6 boots, clean them, inspect for cracks, and the re-attach them. The clamps should be pretty tight. As for the exhaust side, just look for soot build up. That will indicate the source of the leak.

With 192,000 miles it could be the injectors are getting tired. Could also be a worn out spring in the wastegate actuator.
