2003 yukon ls

[JohnsgottaYukon]

Hey apparently I am new to this forum because I just bought a beautiful pewter 2003 Yukon LS. I was wondering what some performance enhancing modifications, for the better, do y'all recommend?
Thanks

Intake and exhaust for sure...

LT headers, intake, ( do you have a 5.3L or a 6.0L ? ) Beef up Trans, lower rear gears, vette Servo, E-fans, Heads, Cam, Tune, Blower, Turbo, drop a Built LQ9 6.0L if ya wanna be NA, or a Built LQ4 if ya wanna go FI. if You have a 6.0L get the TBSS intake and throttle body.


are You wanting all around power ? off the line power? I.E. low end. or mid-range, or more top-End?

what do you use your Yukon for? is it a daily driver or a toy huller? Yours or Wifes?
