Hey everyone,

I am new to this EFILive Life but so far i am way impressed by the way everyone helps each other out! That being said I have a 03 GMC Sierra 2500HD 4WD (LS1b Gen III ) with the 4L80e Transmission. I have a Volant Cold Air Intake w/Underbody Snorkel, Volant Throttle Body Spacer, Pacesetter Long Tube Headers, FlowMaster High Flow Cats with a Magnaflow Dual in/out Muffler. I tow a 30ft toy hauler that weighs about 11,000 lbs Loaded. I am trying to get some extra torque so its not so sluggish and hopefully to help the overheating issues. I am not to worried about gas mileage as the truck is paid off and is alot cheaper than a new truck Is there a tune already set up for this or do i need to start fresh? I have been reading post after post about similar situations but none that match my current setup.

I would appreciate any help i can get!
