I'm going completely stock for my car. I ran 15.3 with it running like crap on bald tires...
Since then I've done maintenance like a mad man. Only thing that will not be stock is the fact that the cats are missing...
I went stock down to the air filter and oil filter even. I didn't like the K&N fouling the maf every few weeks. My goal for the car is to hit high 14's with it in this form.
Then my mod path will have ended until I get myself into a new car... perhaps a Lincoln LS V8....
