Tested vs a 255HP and flows 25% more at 43psi! Definitely uses more amps (13 vs 8) but it's also much quieter. I recently tried a cheaper brand I'll call "O" and two of their 340lph pumps only tested to 180lph.
I've had this pump for a few months running on my car and it hasn't given me any trouble. Whether you want to replace or upgrade it's definitely worth it.
