    What do you mean by: when ever a tuner has trouble with our meter all they need to do is call and we can flow and send them the transfer functions.

    I guess I am assuming when you said

    "The Granatelli MAF was the first bolt on upgrade I did when I first got my car back in 2005. Now I have heads, cam, headers upgrade and it was hard to tune with the aftermarket MAF. Yes they let more air in but it gives the PCM the wrong reading and causing it to run lean. I had big issues with tuning until I put the stock (untouched) back on."


    HArd to tune - that you were tuning with aftermarket software. If you are using an EFI Live style tuning program, it allows you to tell it the MAF transfer functions
