BONE STOCK 99 Camaro Z28, A4, 3.23, LOW MPH in 1/4

UPDATE: I ordered all maintence items. Spark plugs, wires, o2 sensors, fuel filter, and air filter. I installed everything yesterday (and have scars to prove it!)
The car seems to run so much better. There's ALOT more noticeable top end power. All the stuff I pulled off was STOCK except air filter! The fuel filter was a rusty old style ac delco.
Hopefully, I run better. I will see in the next coming months and will update.

No results as of yet.
I would highly recommend you do all the above maintainance, it made a night and day difference.
I'm also adding a dynomax cat back & SLP lid. I'll be curious to see what that will add too.

Well, I went to the track today. It wasn't good.
I ran 13.5 - 13.8 @ 100 - 102 mph. This is after the full tune up, plugs, wires, fuel filter, o2 sensors, and, pcv valve. I also added a Diablo tune, & a SLP lid.
Im starting to believe there is something wrong with the car. I have scanned for codes SEVERAL TIMES. Can not find anything! It runs & drives great, no issues what so ever.
I checked the DA, & it was 156 ft. I also had less than a 1/4 tank of fuel. Any ideas would be greatly appreciated...

Yeah, I had small amount of wheel spin at the start.
I was cutting 2.0 60 fts last time, & now I was cutting 2.1 - 2.2. It was very humid & warm last night. But, I would have at least expected for the mph to be up. My best was a 13.4 @ 102 last time! So, it has dropped 4 tenths and around 2 mph....

Get a cold air intake to open the breather up and once ya see how well that works, nature will take it from there. Be a good idea at that point to take your name off the kids college fund, tho'.
The clock, she's a cruel temptress...

Man you're doing fine. Ya had nasty air which never translates into optimal track conditions, stage gets loose. And if the herd is burning out on street tires, they're carrying loose rubber onto the stage and the track rarely gives the stage it's best work on TnT night. 'Sal good...

I will literly, go in the garage and tear everything down looking for a problem. Haha
What I'm at least grateful about is the mph, it hasn't went under 100 mph. So, the car is making power.

Im just concerned I guess, I just don't want to invest the cash if the car isn't going to return.
I plan on putting a Yank SS4000 stall, long tubes, & tune here soon. The last thing I want is to have it run terrible times. The MPH is already terrible IMO.

Maybe I am. Here is the info from yesterday:
Track Elevation:
154 feet above sea level
Air Temperature: 57.9 F
Barometric Pressure: 30.12 inches Hg
Relative Humidty: 89%
Density altitude: 73 ft above sea level
It felt a lot hotter than 57 degrees. I was sweating while sitting in the staging lanes. It must have been the humidity...

I've cleaned the MAF. And, when cleaning, I didn't notice any debris, and there are no fault codes. I know that doesn't always mean its bad, but it could be possible.
I have no symptoms of a bad MAF, & o2 senso;rs are brand new denso's.
Now, I do have a funky oil pressure gauge that tends to go down a tad when I push on pedal around 2k rpm. And, my oil pressure sits around 35 psi at 600 rpm idle when at operating temp. But, I would think my engine would have blown to pieces when I ran it at the track if I had oil pressure issues. I hot lapped it a couple times too...
