Tune for 07 6.0L truck?

I have a 2007 6.0L gmc hd truck and I am looking for a good strong tune can anybody help? Thanks

Are you tuning it yourself?
Post up your stock tune and a data log...
Reg Cab, Extra Cab, Crew Cab?
Is it Lifted? Lowered? Stock?
Wheel & Tire size?
Transmission?
What fuel do you use 87 octane, 89 octane, 91 octane, 93 octane, racing fuel?
Any mods? Do you have EFI Live?
What do you mean by a "good strong tune"? Towing? Drivability? Performance?
???...:)
