There are not many mods for the 4.2. A chip won't yield you much HP because it is a natural asperated engine (hopefully I spelled that right), meaning its not turbo'd or supercharged. You can add an air system and exhaust. It will help it breathe and sound better but still the HP will be extremely minimal! The horse to modify is the 2.7T! You can check Milltek for the exhaust. GIAC, APR or AWE Tuning for chips and LLTEK. Good Luck!
