Clean your MAF
Bought some CRC MAF cleaner today and took the 5 minutes to clean my MAF while I had the air filter off for cleaning. The filter wasn't very dirty but I clean it every four months anyway. A couple of hours after I finished, I went out to buy a digital scale at Harbor Freight and was shocked when I hit the gas a little taking off from a light and spun the tires. I have an A4 with the 3:15 gears and this car has never really had a problem with spinning the tires at launch. The few times I have had it on the dragstrip it usually spins very little and is hooked within 10 or 12 feet. I had to test this out so I went to my favorite test spot and with traction control off it will go up in smoke now when it never has before. I would have never believed it if someone else had posted the same thing. It doesn't pull any harder than it ever did above 3000 rpm but the off idle and below 2000 rpm's it is noticeably stronger. I have only put 8,500 miles on this car since I bought it from the original owner who never neglected anything on the the car except apparently the MAF. Here in town in normal street traffic it take less peddle to make it move and it feels smoother. Anyway I didn't touch anything but the filter and the MAF.
So I guess my MAF was dirty.

I will have to take it off and look at to know for sure but it looked clean as a whistle when I took the coupler off. I have wanted to take the t.b. off so I could see the back side and look in the manifold. I hear that the manifold can get pretty oily on these engines. The car has

Will have to check mine one of these days. It's great that your car is noticably more responsive.

My car is stock with basically has the same mods you have, the idle is much smoother and the throttle response is really better. Google Mark Shaner he did mine, he's well known on this board and LS1tech. I think the cost was something like $125.

It is ironic that this thread: including a discussion centred around the MAF should come up just now.
Having slight difficulty with my Lexus that I'm currently driving during the winter. All indications seem to point to a fouled MAF; so I went out and got me some CRC MAF Cleaner.
However, while I was researching the issue that I have been having, I noticed that opinions seem to be divided as to whether or not one should touch the MAF; albeit not directly - but with the spray of fluid form a can of CRC.
The MAF contains a very fine and sensitive set of two or three wires typically made of platinum that measures the air. Some believe it should not be tampered with.
See here at the 45 second mark and the 17 minute mark:

I guess it is up to the individual as to whether to clean them or not. Seems to be the most common thought is to spray them but not touch them. I have cleaned them with spray for years on my work trucks with no ill effects. My 2001 GMC 5.3 has over 320k on it. We have changed the plugs and wires on it 4 times and we cleaned the maf each time. So far it seems to be okay. I will keep track of it though. As an aside to all of this, with the exception of 2 water pumps the engine, trans and diff on this truck have never been apart and it still sounds and runs great.
This is the first time I cleaned the maf on my c5.
What alternative is there other than replacing your maf?

Ended up cleaning the MAF and TB myself Monday. Used the CRC MAF cleaner, cleaned and re-oiled the blackwing, let it sit till Tuesday afternoon, put it back together, and off we went. Don't know if it was in my mind or what, but performance seems to be a bit better.....
