No idea who told you I drive an a4 but I definately drive an M6. Stock with DR's it ran 12.5 @ 111.
Relax, 99.9999% of the people who spout times off here have never even been to a track, so one could be conditioned to think that the remaining .0001% of people don't exist.
I still say you have a happy dyno, regardless of what you have heard, without a tune I don't see you making 388 SAE with your mods. You could show me a dyno sheet but it doesn't change the fact that 388 is probably the highest dyno ever for those mods by a good 10-15whp. Many people with solid cam-only LS2's dont even make 420, you're not going to make that with the addition of a ported manifold, which most likely wont even yield any gains at all.

2. I'm hoping to make my biggest gains leaning out my afr.11.4 to 11.8 is really rich at wot. Again, id be happy with 400, 415 to 420 is my goal as a bolt on only.
well on the stock ls2 intake u would waste ur money to port it... it will cost just about as much to get a 90 mm fast. and as far as the hp rateings i have seen alot of gto's dyno up in okc real high. now i will tell u nick i would not go and get a dyno done for 500 dollars. i take mine out to the votech in the auto mechanics department. here in okla. they can dyno and set your af's and i get mine done for 10.00$. i can take my car to the place i had my 04 done and every wed. they have dyno day and for 40.00$ i can get the same done from a respected place. i will tell u when u do get a good tune done u will definately see the difference.
now i do not run my car at the track anymore, as i just do not want to ruin it. the times in my sig was done 2 yrs ago with the stock clutch slipping and burning all the way down the track. my car now has a little under 5000$ in the engine and clutch, that sounded like a very good race between the two of u. power to weight has it's advantages...

The race between us was awesome. The only other race as close as ours was me vs a c5z06. Usually 3rd I start pulling away from most cars, but he inched away until about 5500 rpms in third, where I started inching back on him. 4th gear was what made the difference.

Well, I ran my buddy Nick last night in his 06 LS2 GTO. His car is no joke, runs 12.4-12.5 @ 113-115.
He has headers, exhaust, intake (he can chime in if he has something I missed). Car dyno'd 380whp/390wtqish to the wheels.
I am bolted, BYT tuned. 320/390 Run 12.9 @ 113-115 as well.
Could NOT do a 40 roll last night since it was cold (30*) and I had nothing but spin in 2nd gear from that range (he had the same situation as well). We did 60 rolls instead to compensate for the wheel spin that we both had.
Pulled a 1/4-1/2 car through 3rd and then lost it in 4th where his top end kicked. Ran 4th all the way through and my front bumper was at his rear bumper when I let off the gas. Minimal brake boost (5psi) was done to achieve these results. This was pretty consistent when we got our roll launches good at the same time.
Ross (billigss/sc) hung in there as well - for his mods and what he has I was proud of him and what his stg 2 ss/sc could do. he trapped consistent 106-108 @ 13.7.
Come spring/summer I wanna do a 40 roll against him (Nick with the GTO) to see how she performs as opposed to running out 1 gear and then watching my top end go bye bye
No BS, no extraordinary claims (Nick - GTO owner) is on this site and can attest to these runs (as was Ross - billigss/sc).
Now the cobalt is sitting in the garage waiting to come back out since there is 13 inches of snow on the ground

Do you have video of that GTO running a 12.4-12.5 @ 113-115 sorry but I call bullshit.

I've ran both my cobalt and mustang on the same dyno as Nick. The mustang put down 310whp 299wtq and ran 11.9s at 115mph the same week. The Cobalt put down 291whp and went 108mph on a 95 degree day. It's not a "happy dyno"
*edit* Billig ss/sc - you and I would be a good run. I'll have to join in the next time you guys meet up.

388WHP with intake and full exhaust on the stock tune, my stomach hurts from laughing so hard.
Did you dyno @ Haddad motorsports?
If you think you are making over 400WHP uncorrected on the stock cam you must be smoking sometihng really good.

Well if it was like 30-40 degrees in the shop 400whp Uncorrected could be possible, but I'm assuming the dyno itself is off.
I made 385whp with headers and a tune, but the baseline pull with the headers on before the tune was 365whp.

All you guys dyno on really forgiving dynos or dyno in 30 degree weather and then post your results, which are skewed.

So if you made 385 what's unbelievable about my 388? And then that leaves it open for one to call bullshit on your 11.85 @114. If I'm pulling 12.2 and 12.3 with more whp then you, and probably wtq, where do you make up the 4 tenths that I'm missing??

this site is full of children.
Nick isn't some jackass calling numbers, blah blah blah. His car is quick.
I was at the dragway when he ran 12.4 @ 113. Believe what you want

Most people who live in this country live in cool to cold weather climates. If anything the skewed dynos are coming from places like AZ, FL, TX and CA!

The times don't bother me at all, the dyno numbers a little. But then again if he has full bolt ons and a can tune I can see it, there are full bolt on cars at 400 rwhp (my stock GTO ran 10.9 afr stock, so I would think there is a can tune on there). So 388 with a good tune still left on the table is on the high side of believable, stock tune not so much. I bet he could hit 400 with a UD and good tune, maybe even more with a FAST. Not to mention his trap is indication of a high 300rwhp GTO too.
Remember street tires leave alot of the time on the table but can still have the trap there, or poorly driven DR's...

Absolutely come join us, it was a blast.
It was around 60* and misting, very humid.
So if you made 385 what's unbelievable about my 388? And then that leaves it open for one to call bullshit on your 11.85 @114. If I'm pulling 12.2 and 12.3 with more whp then you, and probably wtq, where do you make up the 4 tenths that I'm missing??

You probably don't really make more whp than me on the same dyno, that's my point.
You're also losing time in the 60 foot. When I ran 11.85 @ 114 my 60' was 1.65.

I understand you are trying to make the point that some shops dynos are more lenient then others, the shop I went to isn't known for having a lenient dyno. In fact I have heard it is slightly stingy.
I hope you have an upgraded clutch, otherwise not quite sure how the stock ls2 clutch held up for a 1.65 60'. Mine would slip and not allow anything better then a 1.77.

Car is rated at 400HP stock. They dyno around 340WHP stock. Why is it so hard to believe that he gained 40WHP from an intake, LT headers, and full exhaust?? Maybe you're new to the LS world, but thats not uncommon. LS engines respond very well to bolt ons.
