Need help on choosing the right MAF... 99 Camaro Z28
In short, I'm getting alot of stumbling and hesitation around 1.5 to 2.5k RPMS and WOT feels like it takes a minute before the power comes in.
Awhile back I replaced my stock MAF with an eBay MAF: https://www.ebay.com/itm/New-Mass-Ai...890?rmvSB=true
Is this an 85mm MAF and if so, does it require a tune to work with an F-Body? If so should I descreen my current MAF and have it tuned?
I did have a harder time getting it into my SLP LID.
If it doesn't require a tune and my MAF is indeed bad, do they still make the stock 75mm MAF's and if so where do I get one? Any part numbers for them? I was "thinking" of getting the MAF sensor only and using de-screened ported ends..

Ive seen stock MAF vs stock MAF have drastically different calibrations so yes any time you change MAF's you'll likely need a recal to verify the transfer function. I wouldn't both doing an 85mm MAF though...either stock or go straight to the LS7 in a 4" tube for big power. But I never like running without screens in the MAF. They do a great job with straightening the airflow across the heating element with minimal restriction.

I was looking at those, what I was concerned about is they may be 85mm MAF's. I heard they no longer make the F-Body MAF so thats why I was concerned.
I dont think so cause the 85mm versions have the 5 pin connector for the integrated IAT sensor and some of the Rock Auto MAFs like the Delphi units are still 3 wire, plus not sure if the 85mm will drop in with a stock/factory coupler.

Verdad Gallardo That is odd. The 85mm are obviously larger in diameter but some of those descriptions on rock auto suck for info. I would only use them for part number hunting.
Can you recommend me a good MAF to go with? AC Delco or SLP 85MM or something else? I have high power goals for the future (looking to make 600 - 700 whp) so Im assuming the stock Delco wouldn't be ideal, but then again I don't wanna spend $400 on a new larger MAF to find it was never the problem either.

I've been looking for a stock maf myself and it's either go with a new cartridge style or go with a remanufactured original style. Both are a bit pricey and both could be temperamental without having someone check them in the tuning software to make sure they're reading correctly. It's not fun trying to deal with sensors on older cars.
