Ever since I boosted my car ticked really bad and was a little slow to spool. The other day I as coming home and hit the hammer and boost only hit 5psi (7 is normal). As I drove it went to 3 then in acceleration it could not get out of VAC and coughed accerating. Turns out the gasket material (paper and metal designed for custom headers) was not high temp enough! burn it out. So the ticking was leaking air and slow spooling too. So always check gaskets and usin oem designed one if your not boosted.

 

I think that's the same ---- I just put for the gaskets between the my turbo and manifold. Glad I didn't put the turbo on yet. I'll have to go get some oem gaskets.
