Here are some things not to do because they will not have an appreciable affect on performance.
1. Air intake- there is little to no advantage of adding an air-intake to a Vigor, especially without a new exhaust, even then, the benefits are minimal at best and you've lost hundreds of $$ on it.
2. Exhaust- once again, an exhaust will not make any real difference in performance because of the Vigor's setup.
3. Chip's- there are no quality mass produced chips for the Vigor because they are so rare, the ones out there are cheap and are mostly ineffective.
In order to increase performance your probably looking at major engine modifications and $$. The Vigor is a luxury vehicle and is meant for smoothness and therefore the Vigor's power comes on as a slower steady rush by design, as opposed to a quick spurt as in an Accord. In the end Vigors are much faster, even though you might not feel it.
