programing/chips for 2003 honda civic?
A person i know with a 2009 civic si got some kind of programing tool that allows him to adjust when his vtec kicks in and his rev limiter, curious as to what your thoughts are on these products, are they safe for your car? Any problems with them? And what company offers a reliable product like this?

Most likely an Apex'i V-AFC...? They're safe, when used properly. If you don't know how to tune, I wouldn't recommend trying to do it. They do work with your injectors and air/fuel systems. If programmed incorrectly you could easily detonate the motor. They can be a good useful starter tool though.
