So I recently rebuilt my throttle body and it will still leaking after putting it back on the car. Well today I removed the throttle body and used a dremel with a soft wire brush to clean and even out both sides of the throttle body, intake manifold, and throttle body elbow. I also placed silicone high temp oil resistance RTV on both sides of the new gaskets and bolted it back together. After 10 hours for the silicone to set the car has no leaks coming from the throttle body anymore! During this 10 hour wait I also decided to rebuild my turbo because it had horrible shaft play and would burn oil. After the rebuild it was so stiff it would not even turn freely I literally had to put force just to get it to spin. I took it apart about 3-4 times and still got the same result, I used assembly lube on all the parts. I have ZERO shaft play absolutely none, and was like I just need to bolt it up to the car and see what happens. At first it would not boost until about 3k RPM and would get stuck at 0 vac/psi after a pull. After a few more miles of driving it started spinning and working great and boost just fine and doesn't burn a drop of oil anymore!

Now... all of these improvements came with some cons. My idle seems to ride around 1.6k and will surge once after pushing in the clutch from about 3k rpm then stays steady at 1.6k rpm. Would my TPS position have anything to do with this? I didn't touch anything on the throttle body besides the TPS and changing the shaft seals of course. Before rebuilding the turbo I would see about 15 psi on my boost gauge which is what the car was tuned at. Now I only see about 11-12 PSI, could this be because of an exhaust manifold leak? Or could it be because I no longer have a throttle body leak and it doesn't have to try as hard to build boost? I have no idea, but my intercooler piping is leak free as well. Exhaust manifold is my only thing I am not sure on.
