Engine 90mm MAF on 94 stroker

Agreed about the calibration sentiments (calibrated generally applies to aftermarket MAF's that are trying to modify or fool factory programing/tuning). The LMAF might have come OEM on a vehicle with 42's, but that vehicle's ECU is probably not being used in the Mustang. The MAF transfer curves (LMAF vs stock Mustang) are different.

In case any of the info is helpful, here's an article with some info.

Good luck and stay safe.

What is the motor combo? I personally find the Lightning meter to be lacking on many fronts depending on power level.....

Even though that 90MM is huge it's very limited. I think it's only rated to 450-475 HP. Anderson Ford Motorsport has the adapter for under $40. I'd sell it and find a Pro-M 80MM. It outflows the 90MM by a long shot and doesn't require an extra adapter. I used the 80MM on my Vortech S-Trim with 42's than a 347 Stroker with 30's. An awesome meter.

I think the 90mm LMAF works well if your engine runs within it's air flow measurement range. If you're pulling stock air flow rates, then it's over-kill. If you're running a high rev stroker with a big cam or forced induction that moves a LOT of air, then it doesn't make sense since you'll peg it.

The JLT cold air system can be adapted very easily to the 90mm LMAF or SCT meter since their tubes are crazy big to begin with. I talked to their sales person last year and she said that they can put together a kit with the right parts, or sell you the parts needed to adapt an LMAF to an existing JLT system. The standard kit came with an elbow that adapts the stock 70mm meter to their giant intake pipe (I think it's something like 5" in diameter) and the 70mm MAF to conical filter adapter, so those three parts will have to be upsized to handle the 90mm MAF.

The down side here is that they stopped making the SN95 5.0 cold air system last year. Some of the JLT distributors might still have a couple of them left in stock if you want to go that route.

Do aftermarket MAF sensors fit inside the stock intake tubing? like the ones from Pro-M? im guessing flanged is the same as stock?

My car likes the 90mm SCT. Its calibrated to the injectors via. the chip.

Whats nice about the SCT and some other models is the extra 2 pins are for the built in IAT sensor. When i installed mine i bought a 6 wire pigtail and soldered the MAF and IAT wires for a much cleaner look. I made a thread about it some time ago on here where it was confirmed by the guru's from eectuning.org. The IAT has no polarity BTW

Yes the flanged unit will bolt up like stock.....
