That shouldn't happen unless there's driver error or the Mustang's modded.

I know the M6 Camaro SS beat the Mustang GT to 100mph by 1.8 sec (Motortrend testing). That's a significant difference.

Be nice if are L99 members would give us their 0 to 60 times, stopwatch it or just count OneOneThousans-Two OneThousand up to 60 to see if there close to motor trends 4.6 time. Any help would be nice.

What I would also like to see is some side by side drag races (from a dead stop) between a stock LS3 Camaro and a stock L99 Camaro so we could see the performance difference.

The LS3 should have a nice advantage at higher speeds (roll racing), but in a drag race from a dead stop, I think the race will be very close (0-60mph & 1/4).

Last night in 94deg weather. Pretty much all stock Camros were running the exact same times L99 or LS3. This was an L99 run...

Cool, I like hearing that, Scott needs to check his to see how far off his is or take it to his dealer. Thanks

No street racing=no problem.

Lots of different combinations were run last night... Here's an LS3 run. I hesitate posting some of these since we were all trying out different things. TC on vs off... Tap Shift vs. not. Bottom line was whether it was L99 or LS3 the times were all right on the 14 mark. Autos left the line better (no wheel spin) and the LS3 caught up down track with better shifting.

This makes me a bit scared. I was on the fence about the L99/LS3. However, my car should be here in a few weeks, so too late for that.

I’m not thrilled either with the poor showing of the L99 on the dynos as well as in the 1/4. Mine feels like it has some dead spots, shifting is soggy, paddle shifting response is terrible, and off the line should feel stronger. On the other hand with these shortcomings and knowing that dyno numbers for the L99 are 50 or more rwhp shy of the LS3, its makes one wonder why its not running significantly slower in the ¼. This tells me the Auto and its gearing have some significant advantages even in its unturned state. It would seem logical to assume that bringing the L99 up to LS3 power standards should give it real advantage to the LS3 M6 combo in the ¼. Tuning the Auto programming and torque management should provide an addition al edge as well. The VVT cam options coming to the market should provide for some broader powerbands then one might otherwise see in a "streatable" LS3 cam combination. On paper things still seem promising. I’ll be watching tuners results to see if this theory holds true. If so, the initial disappoint I see as well as many others, I hope will be pleasantly reversed to one of excitement. LET THE TUNNING BEGIN!

I'm not familiar with Chevy's adaptive learning system but you could unhook the battery for a day/few hours and see if the learning resets itself. Then, let the car know how you want it to perform.

Worth a try, I guess.

That would not effect it.

My L99 times were right with what you are posting in similar weather DA ~3000. Makes me feel a little better I guess...how many miles did you guys have on the odometer on these cars???

[toehead93]

I have not had any trouble with my car at all. I wish torque management had a competitive or off setting though because it really does limit low end torque but even with the stock setting the car will run 0-60 in 4.7 seconds. Keep in mind most of you are racing in 80-90 degree weather so your car is not going to pull as hard as it will in 30-40 degree weather.

If you're looking to mod the car you will be happy, we have VVT and aggressive gearing. Everything you are complaining about can be tuned. Plus we have the advantage of upgrading the torque converter.

[Sledheadrick]

This is nothing new. All of the A4 GTO owners went through the same thing: "A4's suck on the dyno," "Auto trans = no power," etc, etc, etc....


Find a good tuner and have the transmission reprogrammed. Cut off or minimize the torque management, adjust the shift pressure, shift speed and shift points, and if you have the cash, get a 2800 + torque converter. It's worth every penny. The car will haul azz and you'll have a SEG from ear to ear.

I had about 2500 miles on mine and was in the group posting those times with an L99
