I RECENTLY BOUGHT A 06 V6 PREMIUM AND AM READY TO MAKE MY FIRST MODIFICATION. I HAVE BEEN INTRESTED IN THE C&L TRUEFLOW AIR INTAKE SYSTEM FOR MY V6. BUT I'VE BEEN HEARING ALOT ABOUT THE TUNING NEEDED TO BE CHANGED BECAUSE THE CHECK ENGINE LIGHT WILL COME ON AND THE ENGINE WILL RUN RICH. THE DIABLO PREDETOR TUNER HAS BEEN MENTIONED, BUT I WANT TO KNOW IF BUYING A 200 DOLLAR TUNER IS ABSOLUTLY NECCESARY? WHAT OR WHERE CAN I GO TO ADJUST THE TUNING?
