I have a buddy with a 2003 silverado with a 4.8. He wants some boost and im taking a pole to see what you guys think. Here is his choices. RADIX- STS TURBO -Detroit speed works turbo system - ATI procharger- Whipple without electronic bullshit. With that said has anyone used a sts turbo on a lowered truck reason for asking is i seen on some pics that the charge pipe runs under the frame at one point and the subject truck has a 4-6 drop.

 

Radix!

 

My vote goes for radix since its the most complete kit out there!!!!!!!!
