SLP MASS Airflow Sensor Question Gentleman,
I have a 00 vette LS1 with heads, cam headers, 430 RWHP and want to install SLP's mass airflow sensor due to the larger design of the sensor 85mm vs 75mm (97-00) and better airflow. Does the SLP come allready calibrated out of the box or do I have to have the sensor recalibrated for the 01-04 application. In addtition I have a blackwing aircleaner will I have to order the lager bellows for the larger airflow sensor? Any info wuld be apprechiated
v/r

SEARCH!!! 
There are many, many, many posts about the SLP MAF (and messing with the MAF in general)
Long story short, DON'T do it.
Edit: Unless you are confident you can tune for it, but that isn't exactly simple so you should know what you are getting into ahead of time, otherwise leave the thing alone. Actually, my personal take is to leave it alone even if you think you can handle it.

Take a look in the tuning section stickies. There is a good conversation on how the MAF works, and another with great information on what it takes to re-calibrate a MAF. MAF tuning is a very involved process. Unless you have the means to tune for it, it's generally a great idea not to mess with the MAF

my 99 version of the SLP has an electronic circuit that is attached to the MAF. It is supposed to fool the PCM into thinking it has a stock unit... I thought they ask you when you buy it wheather you have a program to alter MAF signals.

The "electronic circuit" on SLP MAFs is a resistor.
On the plus side you also get an adaptor harness
(with three of the 5 wires) and half of a piece of
geniuine Fernco hose. Professional grade.
SLP doesn't ask for anything but your money and
a ship-to address (unless it's SS/Firehawk stuff
and then they want your VIN too).
You can "tune" the MAF by changing out the
resistor for another value. I have done this.
Lower value is leaner, higher value is richer.
But better tools have come along, as have
better deals (MAF-wise) for those who use
them.

What do you mean a lower value? You mean a resistor that basically doesn't resist as much? What exactly could someone replace it with to make it work properly with a headers, slp lid, and cammed car (TR224 on 114 = ) A specific size recommendation would be great! haha
I actually took the resistor out and my car didn't seem to like that. I've been trying to get that thing to work w/o tuning for it by making it NOT trick the computer.
Thanks!
