I was just wondering If I go with a performance MAF will I get any horse power gains and will I notice a difference?And what one is the best?

Welcome Aboard! You can remove the screens in your MAF, and pick up some additional CFM. I would not change it, as other MAFs will not work with your ECM. There are quite a few third gens running real fast with the stock MAF.

why will other MAFs not work with his ecm?

i haven't seen one for a thirdgen. that was much bigger than the stock one anyway. most of the ones i've seen don't say anything about special mods to the ecm.

what 87zJeff says is true from what i've seen.. not to mention they are $425.. so im just gutting my stock one.. lol

They can, but you have to get creative. There are some programmable converters floating around for converting the pulsetrain output of an LT1/LS1 MAF to a 0-5 volt signal. Also, youd have to come up with a work-around for the 255 g/sec limit in the ecm. You could just have all table values represent double the airflow, but then there are serious resolution problems. The code in the computer would ultimatly have to be reworked. It can be done, and I found it works fairly well, but the mods are somewhat involved.

The only thing you can really safely remove is the rear screen. The fins are likely needed to keep the hardware at a safe temp, and the front screen (actually a flow straightener) is definatly needed.

i was referring to aftermarket MAFs such as the granatelli mass air sensors. not an LT1 or LS1.

Waste of money, really no such thing as a high performance Maf Sensor for TPI cars. The Wells Maf was the only higher flowing one out there and now they are hard to find.

The mods to my motor are (ported and polished plenum, 52 mm holly,injectors,cold air intake, complete exhaust,chip,descreened maf,accel ignition,and 410 rear end. Im trying to do at least one thing a year to make it faster.Thats why I was wondering about the MAF casuse it is expensive.So I really appreciate the help so I dont wast my money on something that isnt going to help.....................I would also like to say that this is a awsome web site very well done.,.....Thank you all very much Tony

Yup, upgrading the MAF to a high flow aftermarket unit is a waste of money that could be better spent.

You would be suprised how much a stock MAF really flows..

Cool thanks I appreciate the help

What about the LT1 granatelli mass air sensors because I am about to start my LT1 swap. I'm gather my parts I don’t have and figured since I'm going with a LE2 setup on the top end of the motor the Maf could compliment the intake system.

I've been screenless and finless for quite some time now, no problems. I wouldnt suggest it though on something that doesnt need that crazy kind of modification done to it though.

Cant tell you what gains may have resulted. Did an exhaust change at the same time so the results (which were better) are kind of moot. Most of it was likely the exhaust.

not really looking for a performance MAF although it would be kinda cool, but i want one that is brand new,not rebuilt. the wells have went to the wire filament from what i have heard recently. i have also tried the microtech units and they didn't work on my car either. it was just like not having one. now maybe i got a defect, but it wasn't a good experience. i hate buyiing a rebuilt on something like that because they don't seem as good as new ones do IMO. so if anybody knows of a brand new one, not reman, let me know. the wafer design preferrably as i have heard it is better than the factory design.
