Re: Exhaust and intake
I don't know anything about the S& B intake but the general consensus is the factory Donaldson filter moves more than enough air unless you building a 500+ HP monster and you won;t find a better filter out there as far as filtering ability. Why risk dusting the turbo if it's just going to look pretty but not do anything. Exhaust should lower EGT's, no downside there that I am aware of.
...and yes, a tune is a bad idea without studs, these engines can lift heads with out any software help.
