    Mass Air Question.

    I just bought a 98 SS it has SLP cold air, exhaust, SLP mass air, and some suspension mods. I have the stock meter would I be better off puttin it back in or leavin the SLP one on the car?
    I'm askin cause I've heard you can lose power with aftermarket meter's.

    it will only be a few hp either way. The SLP maf will lean out the engine and probably make a few extra hp, but lean isn't good. I recently took my slp maf off and put on a stock one because i didn't like the idea of it leaning my car out.

    I know lean isn't good. I will probably try the stock one and see how it does.
    Did you really even notice any difference?

    I had the bigger MAF sensor on my 01 SS and once I took it off the car felt like it ran better. I would say go back to the stock MAF sensor. Plenty of Corvette Owners wouldnt mind seeing an 85mm MAF on e-bay, it is how I got rid of mine.

    The stock MAF (screened if it came with one) is good for 500HP--there is really no reason to change it---On a M6 trans sometimes you can get away with using an aftermarket one--However on an A4 it really messes things up. The trans uses engine load and tps to command shifts--so when the MAF is not accurate the trans will not shift at the proper times and the trans pressures are not what they are supposed to be--Long story short--It can cause pre-mature failure---You can re-calibrate the new MAFs but it is a tedious job and WHY ?? 2 rwhp ???? maybe--not worth it--and not worth the risk of tranny damage

    The stock one came with the car when I bought it. I'll throw it back on today or tomorrow just to be on the safe side.
    Thanks for the info.

    I put the stock one back didn't really notice anything. Did some of the stock ones come without a screen? Mine doesn't have one.
    Not sure whether to keep it that way or sell them both and get another stock one with the screen off ebay.

    Its for BENDS!!

    Sounds like someone removed the screen on your setup before you bought it. I have read that this is a common mod to free up some (however minor) HP.

    Also, it was mentioned that the screen is there to strighten the airflow. But this is only if you have bends. Since the Fbods have a straight flow piece, you do not need it. The trucks need it because the airflow is more turbulent with the bends in their intake pipe. The screen cleans it up a bit...or so I've read.

    But for your app, you do not need the screen

    I've been readin quite a bit on it. I read about the bends and it makes since, but everybody is back and forth on it. I'm gonna leave it the way it is for now since I'm havin no problems.
    I also read that aftermarket ones won't lean your car out unless you have a bunch of bolt ons that it's not calibrated for. I wonder if this is true, I'd like to have that SLP one back on if it gave me a little power and didn't hurt anything.
