IF .....big IF.......you need a tuner with that 09 to tow then trailer is too big/heavy and you are towing overweight/beyond ratings.

Needs and wants are 2 different things. I tend to miss my compound turbo Duramax, but I get by with the newer truck and less horsepower.


For the OP, EFI live tuning via a reputable tuner is always the best "safest" (I used the term loosely) was to turn up the power. I would recommend an Autocal from RidgeRunner Diesel Performance.
