I'm building up an '03 vette longblock with a 90mm tb. I already bid on an SLP MAF on Ebay, but now I keep hearing about people having problems with the SLP MAF. I plan on having a completely custom tune when the engine is complete. Do the problems with the SLP MAF arrise from a the need to retune after the mod, or are people actually having problems with the accuracy of the SLP units' measurements. Does the SLP have a devider down the center like stock?

In other words, we're talking about standard hot rod techniques people.
To elaborate, although a 75 mm MAF is not a huge restriction, it isn't very free flowing either, exactly like a stock tb. Once you increase the flow of the MAF, as long as you have a lid that can support it, the motor will be able to pull more air with less resistance, just like any other ported component in the intake track.
Now, it doesn't come without it's disadvantages. It's expensive, in a cost/performance ratio, for one (somewhat like a ported or aftermarket intake). Second, it won't work perfectly without tuning. That is crucial to MAF success in any application, ls1 MAF is no exception. Again, these are characteristics that you have to weight against your entire combo to see if a MAF is really right for you.

Probably Tweaks The Out-put Of The Intake Air Temperature Sensor So That The Ecu Thinks The The Air Is Colder Than It Actually Is To Allow More Timing Advance, Hence Extra Hp. Talk About Some Stone Age Tuning. Why Don't We All Just Tweak Our Fuel Pressure Regulator While We're At It?
I went with the ls6 one from PACE, where it's all from: the MAF, the pig tail connector harness (including IAT sensor built-in), and the transition rubber component.
I like the characteristic you can purchase all that is required from just one place, not to mention a place that not only is familiar with the sort of component replacement but also have a history of great success.
