I ran a nx wet kit on my 03 with a 100 shot un-tuned. I ran some colder plugs and retarted the timing with my sct tuner by like 2 degrees. Also ran 93 octane gasoline. Your buddy should be fine on this setup, mine was. My car ran strong as hell. I am trying to get my car tuned this year tho because I'm getting some longtubes and cams for the car.
