Based on my experience, the PSI rating usually fall very close to 40 PSI stock. I don't no know of stock flow but I upgraded my Cobra to a 190 LPH pump with an inline t-rex pusher pump that could hold 255lph. That got me 425rwhp. I just went 255lph in tank pump as well to keep up with in line pump. the price difference between 190lph and 255lph was $10 dollars. Go for the bigger one if all else equals out.
