I dynoed yesterday my 2010 Cayenne Turbo, what has 200'000km(125'000 miles) on board
Car is bone stock, except removed secondary cats. Plus side it has plenty of heavy addons like Burmester, 21" rims, PDCC, PTV+, heat insulating glasses, 4-zone clime so weighting about 2400kg(5300lbs)

And it got healthy 502hp and 561 ft-lb
It's from engine and computed 20% drivetrain loss.



502hj ning 761nm

Here is video
After that I take this device http://racing.qstarz.com/Products/LT-Q6000.html and tried 1/4 mile.

First try and 12.7@107mph
Video - 0-60mph takes 4.5sec



Car itself -

 

Well done. Sounds like you got a really good one! Glad to hear it's still going so strong too!

 

Very Nice! Those things are meant to be driven. I am at +80,000km and the climate in this part of the world is tough on cars. Great shots btw !

What dyno is that? and which gear did you use?

 

Removed secondary cats will help augment any slight power loss. But very impressive nonetheless with 125,000 miles on the odometer. Good job!

 

Dyno is Dynojet.

Which one is best ECU tune for 958 cayenne tt?

 

You can't go wrong with GIAC! Just yesterday I switched back to the stock tune, after months of driving with the GIAC tune to take my car in for service. It really felt like I lost 100hp .

 

Your CTT has aged beautifully. Like i keep telling customers/clients - if you maintain these cars correctly - they will reward you with not only the driving experience but reliable ownership experiences.

And yes - GIAC all day, everyday!
