at first the pcm would be sent off and reprogrammed by certain folks
on a stage I the trq managment would be turnd off on qc's and up the fuel an timing a little
on a stage II same thing but extreme timing and fuel
on tunes for the sct I usually suggest three
one a valet tune for security reasons
a second tune for the best grade fuel you can purchase or usually buy
the last tune can be specialized such as nos or have it tuned for mpg, or a lower octane tune for traveling.
