If you go with a 38 in the rear and still use the 16 up front, I don't know that you'll be able to roll from a start in 1st.

Final drive gearing alone is going to drop from 2.56 (with 16T) down to 2.37... That's a crazy amount of difference.
The switch from factory 15T to a 16T up front lowers the final drive from 2.73 to 2.56. You're going to double that drop if you go with a 16/38 combo. So you would be looking at going from the stock 2.73 down to 2.37.... I wouldn't do that.

15/38 would give you a 2.53, which isn't all that different from simply leaving in the 16T. If you want to do this, I wouldn't go lower than a 40T in the rear, which is only a 1 tooth drop and will give you an overall drive ratio of 2.5 even.
