I'm getting the XRT and a 5" tbe coming in along with gauges and some other stuff. I was wondering if I should get a new gasket for between the manifold/turbo? I plan on taking it off to drill and tap the exhaust manifold for the EGT probe. Also, how would you recommend I clean out the turbo in case I find any deposits? I hear alot of people preach about using Sea Foam?
