Drag Racing Results - Why is my car so SLOW!

Well, finally took it to the track today and got some numbers. First two passes were pretty identical.
60-2.0
1/4-14.0
MPH-98
Mods are in the sig, what could be making my car runs so slow? Temps were in the 60-70's, traction was not an issue it just doesnt make any power. FP is 62 at idle and only drops to about 59-60 during a run. Motor has 79k on it.
Put a stock tune back in it and it went 14.7 at 93, so its not in the tune.
Any ideas would be greatly appreciated!

might need a really good tune but still i would think you would be faster than that atleast 13.0 12.90's

does your temp gauge work? i know after i did my lt install i forgot to plug it back in and it ran like shit, i have same mods but true duals and i run an 8.2-8.4 1/8th on bald street tires. somethings very wrong.

also your 60 ft. is decent but trap speeds are way low, did you get and 1/8th mile time on your slip?

make sure your throttle body is opening all the way!!!

Temp guage is working and have a 160 stat, fans are also programmed to come on sooner.
Have done the throttle body 90* check, and is opening all the way.
Here is the breakdown of the best slip;
RT .710
60' 2.029
330 5.924
1/8 9.079
mph 78.70
1/4 14.050
mph 98.78
Could my convertor be junk and slipping this much?

What was the DA on the pass?

What track? And date? Time? I'm curious to see what the DA was.

Not sure what the DA was, but it was at Firebird International in Maricopa AZ today.
As a reference there was a TA with a lid and a catback running 13.6.

I don't know the exact time you ran but your DA was roughly 3000-3700. That is not very good.
Corrected = 13.426 @ 103.304 MPH
Could be a bit faster.. But I don't think your times are that bad..
Pacesetter LT's ORY Magnaflow catback - will give more mph that ET.. you probably picked up 1/10th to 2/10ths
pcmforlesstune- obviously it helped.. but i am NOT a fan of them
315 Nitto's- your sixty was still a 2.0.. you shouldnt really need drag radials
LS6 intake- more mph than anything..
Get a converter.

I have seen someone turned there fans on for a run and lost alot of time. I don't remember numbers but it was .75 I think. Maybe with your fans set cool they are running and drawing amperage and messing with airflow.

whats the elevation there? its at sea level right? that seems weird, are you running better than you did stock, i mean a noticeable difference after the install of all your mods?

Does not matter the elevation.. I posted about what his DA was on that run.

first thing is first, give it a good tune up. CLEAN THE MAF!!!!!! and CHANGE THE PLUGS!!!!!

Done and done, when I got the car it was running crappy so I did plugs, cleaned filter and MAF, and put a fuel filter in it.. I was told that it might have clogged cats so thats when I put the LT's and ORY on. That was the first pass I made with the car, so I have no other baseline.
I still think that if a chick in a TA with a lid and a catback (and 140k) can pull of 13.6's I should be at least that fast!

the car is down on power, but moreso on the back half where it can stretch its legs. you're only gaining 20mph. you should be gaining at least 22-24. what rpm is the car shifting? any torque management changes?
and if that chick disappointed you...my wife went 13.4 @ 109 in a stock 99 m6 ws6 with a lid and flowmaster weld in haha. sucked for be me because it took headers and an ls6 intake in my 00 a4 car to trap that. but for some reason that ta picks up 25-27 mph on the backhalf. fucking freak.

Thanks youre doing a great job of making me feel better, LOL!
Torque mangement is disabled and was shifting right around 6k (just leaving it in drive)

Torque mangement is disabled and was shifting right around 6k (just leaving it in drive)well, with that being said. if at all possible, i'd have a live tune thrown on that car and go from there. let me reiterate...a live, GOOD, tune. i don't believe any mail-order tune is optimal. there isn't much to these cars. if the parts are installed correctly and the car isn't seeing any codes, it almost has to lie in the tune. a good live tuner can tell you what your trans is doing.

My GF's times are in sig.:lol:
And yes, I would look at the tune, when you first posted PCM I thought it would end up being the culprit.

my buddies formula with a lid, headers, and stock exhaust was running 13.20's at speedworld which is very similar DA.

How do you know what the DA was?
DA of a track chances all the time.

true but theyre about 40-50 miles apart.. temperatures can vary by 10 or so degrees around phoenix, but not enough to make a car with more mods run a second slower than a near stock car. somethings fishy with the OP's car.
firebirds DA at around 4pm oct 10th:3360
Speedworlds DA around 4pm oct 10th:4578
my friend ran around 10 pm with the DA was 2885 at speedworld.. granted its alot better than 3360, but depending on when the OP ran id assume they were withing 500 feet of eachother.

I had a similar prob it was my mass air meter.:barf:
The DA is pretty high at my track and I ran a 14.0 stock at 101-103 I was trapping with a 2.3 60ft best. After headers and exhaust I still ran a 14.0 but trapped around 106-109 this time. Something seems off, if your 60ft sucked or your trap was higher it would seem normal but idk

Something to think about, I still have a hard time blaming the tune. A car with a stock tune should still trap as high or higher than me. When we put the factory tune back in it dropped 3-5 mph, which tells me its doing something.
I need to see if I can get it data logged, and see exactly whats going on.

Well I got done putting an intake gasket and an alternator on the buick, and decided to screw around with the Camaro.
My brother said I should try pulling the MAF connector and seeing how it acted. Pulled it and wow, what a difference. It went from laying 3-5 ft of rubber in first to pretty much all of first gear.
I would assume I need a MAF:D

try just cleaning it first. a can of MAF cleaner is only $5 and may save you from having to buy a whole new one.

Check the wires on the MAF, if any of them are messed up in anyway it will make the car run like poo. You can try and clean it first though, but it still may be in the tune, bc what you did by unplugging it was send it into SD.

Cleaned it and it runs good, still. It was really dirty! Took about 5 q-tips to get it all off, but much better now!
Thanks

I have my fans on everytime the car is on. It doesn't slow it down.
