so i just recently want to start modding my SHO this summer before the convention, etc. i was looking at k&n air filters, exhaust and possibly rims/ tires. right now my SHO is my daily and dont feel like modding it in the cold lol. so what are some mods that you guys have, also wondering if anyone had computer issues when adding the feature(for some reason my dad thinks what ever i add to the car engine wise itll f*** up the computer system.) thanks.
