I need a new mass air meter

What are you guys running for mass air meters and how much horsepower do you have? I maxed out my sct ba2400 at 381 rwhp. I dont want to get the ba2800 if its not gonna let me grow much. What other meters or options are there?
 
I have a blow through procharger setup. The voltage was 4.96 at 5600 rpm so we had to cut the dyno run short. Im putting my exhaust on right now and i need to get it re tuned when im done but it will max out even sooner. Prochargers seem to have this problem because the small piping increases the velocity past the maf. I have asked befor if there could be something wrong with the tune but everyone said that the tune doesnt affect the maf cause the maf just puts out a voltage to airflow signal. You cant adjust it with the tune. Also dont ever buy the 2400 cause its the same cost as the 2800. Might as well get the big one.
