Hey guys,

I have been searching and searching... and have found alot of great info!!!

My main question is this.

I just bought an 07 Silverado Crew cab Sierra 1500. It has the 5.3L with an Auto. I have added a catback gibson exhaust, and lifted the truck 6" and put 35's on the truck. This is where the trouble lies... because now it literally feels like I have lost 100 HP. At this point, a power adder is needed and Im torn between either a supercharger or Turbo. Im really only looking for reliability with the most power increase. I do have a race car and some dirtbikes so I do tow pretty frequently.

What are my options? Magnacharger? Vortech? Turbo? I'm hoping some of you guys have some real life experience with any of the above, and can lead me in the right direction. what is the best, most reliable way to get an extra 100 HP?
