Why are you taking the tuner off?
As far as "old fashioned" the first things that comes to mind are:
Quick spooling turbo (PS62, Aurora 3000, etc),
Slightly bigger stix
Arson II kit
AirDog 150
IMHO though, this would all be a waste without performance software (i.e. tuner or downloader) to enable the ECM to make full use of the added goodies...
Just my $0.02
Good luck
