    3.8/speed density

    I have a 2001/Pontiac firebird . 70mm on e85 . right now I'm at 11psi and the maf is maxed . so is there a speed density option for our cars or another way we can tune for more boost?

    Run a different MAF.

    People run the N* maf or a LQ4 maf sensor all the time.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    It's still going to max out I think from what I have read.

    can HP Tuners make a custom mass airflow hZ and extend the table so they go pass 11.5000 hz?
