what would be the best tuner for the 04.5 LLY for towing ? I pull a 30ft 5th wheel weighs about 9000lbs loaded.

PPE makes a good product, I am totally happy with mine. I here a lot of people like diablo sport predator also.

EFI Live is the most versatle.

EFI live or PPE, whatever you prefer those two will have what almost anyone requires.

EFI, hands down.

The handheld manufacturers do not address some issues critical to the way a VVT controls boost under prolonged high load conditions. Certain tunes might be labeled "tow tunes" but I assure you, the issues unique to towing are not addressed, these are just mini performance tunes.

I have had good luck with Edge so far.
