You can use a 3 BAR ZR1/LSA map sensor but on a 2008 I think you need the plug connector as well, then you just need to match the wires up. You'll need a wiring diagram or search to see if someone has posted it on here. The later NNBS trucks like 2010-2011 and later it's direct plug and play.

No sure if the LS1 style has the same plug as your truck or not.

Magnaflow makes high flow cats, they seem to be pretty decent.

No need to mess with any of the brake boost or EVAP stuff, that can all be left stock. The motor will always create vacuum out of boost, it's just going to go away because a turbo was installed.

You'll need a custom tune with someone other than the diablo tune once you install the turbo kit.
