Most of the Race-level files all put out around 425RWHP without FICM tuning. What really makes one tune feel better than another is how the transmission shifts.
I like X-Race, (which is the same file as the Anarchy) and I'll stay with it because I like the firmness of the shifts.
SPD is having great reviews, and putting down great numbers on modified trucks, it shifts very smooth (as I witnessed this past weekend in an friends '04).
Really depends on what you want out of the truck for street manners.
