first off, i'd like to know what my best bang for my buck will be as far as price to hp mods for a 3.8L v6. i currently have flowmaster Y-pipe, and K&N air filter. Sure it's not the most expensive stuff, but it's a start. Now, if there is anything i can get done for under, say $150, i'd like to be in the know. Someone said a new thermometer and i could get a performance chip that wouldn't kill my engine. Now, $150 is not my absolute limit, i'll go up to close to $1K, but it will just take a little longer to get hte money up.
