Art, do you have the full fuel upgrade (997 rails, injectors, etc?). I assume you have GT28's?
For you to be able to pull the Lambo like you did, you have to be making close to 675HP at the crank (maybe more). The Lambo is at 675HP and he does not have to modulate a clutch and shifter. Also, he reves his car to 8000rpm before shifting.

I have carbon fiber air intake and carbon fiber mirror covers for 996TT. Look under automotive parts for pics. Let me know if anyone is interested. Brand new in box.
Here it is gentlemen. 3000ft elevation, race program, 89 degrees this time, WOW. Sam I bet this car would do 620+HP in colder weather, I love the results. Check out the torque guys, I leave this one up to you to read. Add 200 pounds of more torque on top off a Carerra Gt=???
Very nice numbers Art. Looks like you got full boost at 4200 RPM on pump and 4400 RPM on race. How much boost on pump and race? What turbos do you have? GT2860? One thing i noticed is there is a dip at 6400 RPM on both graphs, what happen there? If that can be fixed the graph will looks much better>>>area under the curves

Right were I thought it would land. Enjoy and be safe.
Anthracite, the turbo's are a GT-28 blend. We go for 1.4 in pump and 1.5 in race. The tq had to be eased in on race. Garrett is all about smooth and reliable. The power drop is coming in along with a rich spot. Could be anything like elevation, temp. A little to do with safety too.
Seal grey, the afr's are after the cat. We have seen that spike for a second at peak and it looks o.k. on good race fuel.
Thanks for your observations and input guys. By the way in all fairness to ourselves and any tuner, the turbo's are at around 80-82% at those numbers. More peaks can be achieved but that is not the goal. Good numbers are yes, but mainly a good power band/delivery and engine longevity.
