Would Like to get some opinions on what I should possibly do to maximize the upgrades I'm wanting to do on my 02' Chev C/C S/B Silverado Duramax LB7.
I purchased Edge juice w/ ***. Monitor, Bully Dog Powerpup, K&n Air Intake, and looking into a 4" exhaust system.

Good choices but a tranny upgrade is now essential to utlize the full potential. Some were close to 500 rwhp is not that far in your distantt future. Have some fun!
