Summit can get you one fast… I had one in 4 days dropped shipped from K&N $64 with shipping… Could tell the difference right away and I want to say it change the sound a small amount…

[2SSRS@Gen5diy]

I got one today for free.

Sure sounds like its a PITA...

Glad you have some base line numbers to work with now, I hope your dealer give you a tune/flash= I'll be interested to see what your dealer does for you now. good luck

Ok. So if you had to make a guess. Would you say it's very likely my car is running fine, or do you think the guy that did my car is incompetant, or just has bad equipment?

Also, do you think the fuel mixture thing is reading wrong and my car is breathing better than that?

I'd seriously take your car to another shop and get it dynoed. Look at it this way, you already have this set of numbers so if you take it to another reputable shop and get the same results you have that much more in proof to take to your dealer and show them some thing is not right.

My guess is bad fuel pump or injectors.

So how many dynos does he need to do before the results are good? 5? 10? Does he need to take it to a track next?

Seriously, there's an issue and everyone can see it. Now he has cold hard data to show it.

My L99 hop's around on the Tach,about 100 too 200rpm's and talked too the Mechanic and he said its a lean roll cause of the lean fuel mixture and injectors need a few thousand k too seat,driving the bag off your new hot rod is not the way too break it in and suspect some of the problems are compounded from the driver ripping the bag off the car before its time too do so

IRPQ..

I have some friendly advise...You have to drive it to the home of the Daytona 500. I think that's in Talladega.. And run some laps there.. Then you have to take it to the Nürburgring, and compare it to the Camaro run there.. Save all your timed official runs.. Then just for the heck of it take it to those Top Gear guys in the UK and have The Stig run it around the track as the official Camaro V8 time..I think by then GM will do something about your speed..

Hay this is how the L99 ECM is programed "FAT AS A PIG".

If that by that you mean running the car hard as soon as you get it....well should have done some background reading, irpq babied his car, followed the recomended break-in instructions, and changed his oil...at about 850 miles i think.....in fact, there have been others thats suggested his car was so slow because he was so easy on it.

Clearly an issue. Time to take a stand, give it to the dealer and tell them either they fix the problem so you get the advertised performance, or you get a new car.

I mean, its so obvious that something is wrong, its NOT your responsibility to find out what it is and fix it....that what the frigging warranty is for!

Honestly, this is how these cars are factory tuned. They are set up to run a high 10 to low 11 Air/fuel at WOT. Looking at the power enrichment table in the factory cal it is at 1.32 to 1.34 in most of the HP band which equates to a 10.97 air/fuel (14.7 divided by 1.34 = 10.97 WOT air fuel). I'm not sure why GM is commanding such a rich air/fuel on these cars, the LS3's are typical GM rich in the 11.5 to 12.0 range, but the high 10's to low 11's on the L99's reminds me of how bad they do on the stock tune on the trucks. The timing is also very weak on the L99 factory tunes and there looks to be a lot of gains to be had on these tunes. Once I get one on the dyno instead of just a street tune I will get some before and after numbers up.
The six speed auto is good for 20 to 22 % drivetrain loss at least based on Vettes and STS-V's I have dyno tuned. Only the M6 is going to give you a 15 to 17% loss. The A6 is pretty heavily built for strength and that eats up power to the tires.
Really there is nothing wrong with your car, that is just how it is programmed from the factory and the dealer has no way to fix that.
Something in the 320 to the tire range is what I would expect one of these to make to the tire stock. 400 X .8 (just a 20% drivetrain loss) is 320HP.

That is right it is pulling timing like the truck and is also rich i was tolled all this from the guys at Vararam and the timing is baked out at 2500 RPM and up. This is do to the heat and humidity if you look at his Dyno's his first one has 49% humidity 2nd has 42% and 3rd has 37% humidity so you see the more humidity the more it pulls timing and the lower the HP in the car.

Do you have a scan of the results. 11.5 is certainly not what I was getting.

It would give him a chance to drive one. lol

So you think my mixture is satisfactory?
