    Just because it 'sounds' like it is doing something....doesn't mean it is.

    The airbox lid is a GREAT mod.
    The MAF is a terrible mod (unless you drop ANOTHER $450+ for a dyno tune along with it).

    Why would you need a dyno tune to flow more air? If I hear my air intake flowing more air then it must be doing something. The engine is basically an air pump, more air in and your freeing up more HP. The MAF is not a terrible mod, you may not like them but you cant say it is terrible.

    With any aftermarket MAF, you 'should' get a tune for it. Things change, thats as easy and quickly I can state it. The stock MAF is the only MAF that the computer knows, stick a different MAF in there with different values and you can do damage to your engine. Its just that simple.

    Not worth the price needs to be added in there

    Heres a picture for a stock MAF(well what my file had for the 'stock' MAF)

    The price was listed one post up! $450.00. If everyone is so down on this GRANATELLI MAF sensor then they should say something to the site administrators or who ever is responsible for that HUGE add up top of every page! Claiming 10-15 HP.

    I did not need a tune when I added my lid and that flows more air. What kind of damage can be caused? Somone also said I would damage my car with my SUPERCHIPS handheld, after 2 years my car still runs awesome. I would like to get the most power I can without opening my engine. With the price of the MAF and handheld I know I could have a set of long tubes on with free flowing cats by now, but live and learn! Thats next.

    Exactly. Until you post up a scan from HP tuner or EFI Live, you have zero idea what your AFR is... and Im betting its not were its supposed to be.

    I would guess 14.5/1 or 15/1 or even higher.

    Money talks....


    But what do I know??


    The aftermarket MAF's (SLP, Granatelli, etc) basicly require a tune to keep your car running correctly.
    The stock MAF is calibrated the BEST for our set-ups. While the computer can adjust for airflow in and out, the MAF is one of the sensors that makes said adjustments.
    People have had issues with detonation JUST BECAUSE OF AN AFTERMARKET MAF. Not worth popping a motor for that 10 RWHP.....which is just a result of running leaner and NOT from added airflow.
    You do not max out the stock MAF until 500+ RWHP....

    I would have to disagree with this .... If you install a MAF the you are getting more air which your car would be more responsive to which wouldn't necessarily add power but the car should be more responsive right? Which would "feel" like HP ... as for the hand held tuners I installed a Hypertech with the 160 thermostat and although it may of not added HP the car is more responsive and feels like it runs a lot smoother especially here with this Texas weather

    Get a real tune and you will want to toss the HyperTech in the river.

    I lived the GMAF prophecy for awhile... then I got a tune and found it to be running me very very lean. I went back to a stock maf and whamo, ran perfect and smooth again. Big SOTP difference at WOT. My A/F ratio back in the safe zone!
