Default MAF replacement

Alright so MAF is toast. Been so since Nov. but only learned about it two weeks ago, found out my 24x setup got tuned speed density. I guess I want to get back on a MAF unless there is awesome reasons not to. So looking at Rock Auto:

Standard Motor Products: $102
BWD: $106
Delphi: $114
Cardone: $103
Python: $96
AC Delco: $167
Cardone Select: $167
Airtex: $309 (WTF?!)
Ac Delco Reman: $139

So what is the word on replacement MAF's? Buy AC Delco new and don't even think of anyone else?

Also where can I purchase a 1LE elbow? Contemplating getting rid of my trick flow ceramic coated elbow. I've heard people say the 1LE flows better. I had thought about doing the LS1 lid setup but not sure yet.... Not sure how much work I would need to do to get it to fit under my Harwood hood? Anyone use the LS1 radiator shroud and not have to butcher up their hood on their Camaro? Maybe I will go that route. Perhaps I'll look into the lid setup.

I have an original GM MAF out of my '97, perfect working order. $40 will ship it to your door.
But, there's nothing wrong with going speed density. Your choice.

Thanks for the offer, but I think I'm going to lean towards new. I just want no potential excuses on parts issues when I go back to the tuner again.

How about the Delphi unit over the AC Delco?

I like how dead this thread is, what no one around here ever have a MAF die on them?

Not really...I'm sure there's some, but MAF's usually don't die unless they're dropped or de-screened and something hits the sensor.
If I remember correctly, Delphi produces the electronic components of Delco parts.
I don't think you could go wrong either way.

If the car was tuned for speed density than why not leave the maf out?

I want to get a working MAF again, I travel FL to PA at least once a year. I have no idea where I might be driving it next. I always heard that with a MAF the car will run better with elevation changes? I've also heard it is more accurate in upper RPMS.

All I know is the tuner claims it will run smoother if I am back on a MAF tune. Hopefully its not a bunch of malarkey.

Well I guess Delphi vs. AC Delco and such doesn't matter. Even though Rock Auto said they had one Delphi left they call me today and say nope they are out. So I settled for the reman BWD(30 day warranty so if it is DOA at least I'm not SOL). At this point I suppose I don't care who makes the MAF. Of course the phone person only listed ones that cost higher than the Delphi. Um no.

I would have opted for a used one. LT1 MAFs are pretty robust.

Well that is a good question, as before I did my 24x conversion the factory LT1 OBD I computer hadn't set a code for the MAF. When I took the car to go get tuned that is when I was informed the OBD II computer was not happy with my MAF.

So as an update the first one was DOA, two of the three resistors were broken.
Its replacement shows up today, one of the resistors is bent. Will this affect the MAFs performance? In my mind it shouldn't, but if it is going to then I will send it back and get one locally.

I know.....

So no one has answered the question though.... if it is bent, but not broken, no good or what? Would like to know so if it needs to go back I'm going to cancel it as I don't believe a third shot at it will result in better results.

keep it in SD... no reason to use a MAF. If your car is fully tuned, it shouldn't change even when you change altitude because your MAP values will change accordingly. Obviously if you get your car tuned at a high elevation, you will have to touch up the high kPa areas that you never saw at high altitude.

Car was tuned in FL, so now I'm confused. I don't want to have to mess with the tune every time I go traveling, not that I have the tools myself to do so anyway.

So is anyone going to answer my current question, is a bent resistor no good? Need to know.

It can be bent and still fully functional. To be honest I think your making a big deal out of it, there are many SPEED DENSITY cars that travel and don't have issues.

They didn't sell colorado tuned 93 Lt1s from the factory...
They didn't sell florida tuned 93 Lt1s from the factory...

They are the same maf-less SD tune... Works in both elevations... The MAP takes care of your elevation.
