Hello everyone I am new here to the forums and just bout a 04 Silverado believe the color is SS blue and so far I love it. It only has 30,000 miles on it and I couldn't be more pleased but I am wanting more power out of the 5.3L. My family is huge Mopar fans so they eat sleep and breath Hemi lol. As far as upgrades which would you get first and so on........And what manufacturer would you go with any and all help would be appreciated. Oh yeah I bought an extra 3yr 36,000 mile bumper to bumper warranty and I don't want to void that.

 

Welcome to the forum! You may want to go with a cold air intake and exhaust first and see what you can get out of it. As far as brands go, each is as good as the next.

 

Read the threads in this forum titled "K&N vs. the other guys, and Performance chip," to get good suggestions on intakes and performance chips and programmers. Welcome to the forum!
