hey guys i m new here and i have been doing work on my truck, a lot of upgrading (air-doc, throttle body spacer, truxada front leveling system, magna exhaust, defenderworx chrome installed). was shot down recently by whipple because their supercharger systems dont come ready for any hummer. i was aiming for 530 horsepower to 550 horsepower from my 5.3L. would love to hear what you guys have to say. ps will post pics of my truck.

 

this is my truck

 

hope this works

 

Welcome to HF fellow Montrealers.
