    Very unlikely you maxed it. Check your logs and look at about 5800rpm thats when they go straight maf and usually you might get a bump there. Are you logging maf??? That be one easy way to see if you maxed it.

    the scan file, and the dyno sheet when it cut

    you are most definitely not maxing it out. I'm running a big ass turbo and over 400whp and still not maxing it.
    btw do a log, max hz read by the comp is 11,111hz, if you are hitting that, you are actually maxing out your injectors not the maf itself

    You have to log the MAF.
