Not sure if it is still available but Whipple and Magnacharger are having a big sale on their kits, that we cannot compete with. We would be happy to help with tuning via our AutoCal.
I appreciate you looking out and all but i was told that there is no supercharger currently available for my year truck. Oh well guess i will be re building with high performance parts.

It depends on if you have drive by wire or cable throttle. 2002 was the year they changed mid year. 2002 DBW can use a blower for 2003 trucks, which is what I used on my 02 Denali.

They look very different. Go to RockAuto and look at the throttle body for the 2003 and compare it to the throttle body for 2001 and then see what you have.

Also the drive by cable has an actual throttle cable going to the TB and the DBW just has an electrical connection at the TB.

You should be set then. You can check your RPO codes inside your glovebox and look for KUP which is Electronic Throttle Control, just to be sure. Then you can talk to Blackbear Performance and they will help you order a blower, they helped me with the correct one.
