I have an 03 silverado 5.3 with the magnuson supper charger that i am selling. I have a friend who has a 03 denali. He is thinking of buying the supercharger before I sell the truck, but wondering if there is anything else or different he would need to get to work on his truck.

 

He would need to get his truck tuned. As long as you took everything of your truck that has to do with the blower includeing the in line fuel pump he would be all set.

 

Calibration change, smaller pulley for the added displacement and a new sub assembly for the in-tank fuel pump as the Denali uses a different pump module. We don't remove the in-tank pump when customers want their systems removed because some parts in the pump kit can only be used once and for the cost of a new sub assembly, it isn't worth the trouble.
