I wish I had gone with the 5.3 with LT trim and the 6-speed instead of the 4-speed it has.

Adding a DiabloSport Trinity gave me the power I was looking for, but still think I should have gone with the 5.3 in the first place....next time I guess.

....although, with these recent 5.3L AFM problem threads....maybe I'm better off?
Pretty much any tuner can turn off the AFM.
