exhaust and intake mods will get you a few more HP...Possibly something you can feel, but not a huge amount. Has been fair0ly well covered in this section before. I agree that supercharging is asking for many more headaches. Some that I can think of right off the bat and others that I am sure that I would miss. Be sure to make sure your computer curve can keep up with the air and fuel flow that you add when doing any mods. Modding a computer controlled motor is not like throwing some headers on the old Chevy and then re-jetting the carb.
