Wow. Great info. Can't believe P would do this. Sorry to ask a dumb question but you wouldn't happened to have a link you can post or know where to still find this info would you?

Off topic, congrats on your 700+HP CTT. I am very interested in getting PTT in that range. Would you mind sharing your mods?

 

Can someone please post This letter. Part numbers Are different.

 

I cant believe this. This is fraud!!!

Again, Porsche is using the same strategy with 991Turbo and 991TS, Panamera Turbo and PTS and Cayenne Turbo and CTS, ie same hardware on each with only ecu program change + "S" script. All other specs can be ordered on the base Turbo to match TS. That said, the TS package seems to be a value if you are ordering a fully spec'd 991 Turbo vs TS. However, I'm learning that the 991TS should not be modified much beyond current power levels due to power handling limitations of PDK. The regular 991Turbo can be modded to TS levels but not much beyond for the same reasons. Not sure what the next gen Panamera in 2016 may bring in terms of h/w specs, but the new facelift version will be the same as current cars. Current model Panamera Turbo's are excellent with a few not over the top mods as previously mentioned in this thread.

 

I talked to a P mechanic today. He thinks the intake plenum may be bigger on the S. I also think the power kit might still be available for the panamera. I might be cool to see what is included with that.

 

Basically goes back to what I've said repeatedly - not worth the extra money. I got duped into thinking the turbo S had quicker spool times and less turbo lag because of titanium impellers and reality is they are no different so I overpaid by $20,000 - Yeah for me! Thanks Porsche!

 

Sucker (S got it?)

I would say that the S besides being a more distinct kind of animal, HAS to HAVE better software mapping to account for the extra 50 horses, yes you can do it with a 3K tune and save the other $17 jelly beans BUT imagine the S with a tune, there are already 50 horses to start with.

If I had the money AND I wouldn't miss it, I would still get the S just for having a better/faster car.

But yeah I would miss the extra loot, so I settled for the non S.

Enjoy it as it's a great car with great features!

 

I was just about to post this link for you, but you beat me to it!

 

If the difference is only in DME programming (mainly bumped boost levels), then an aftermarket Turbo tune would be easily able to match and exceed stock Turbo S DME programming.

I have to admit, after doing some research on the PTT vs PTTS, I am not seeing the value either.

 

Thanks! Believe it or not, I really only have bolt-ons that I did myself in my shop. Included the 82mm CTTS TB/manifold combination. Most of my mods are well documented over in Cayenne section. Here are a few main links:

Was talking to a few tuners on this subject a while back while selecting on the Turbo or Turbo S, one thing they said were; even though Turbo S is a high output software mapping, it is still limit/govern by the strict law of US to get approved to sell here (ex. smog). But aftermarket tune opens up and optimize the engine potential without having to deal with governing laws and restrictions (ex. GIAC).
I can tell you from 11 pulls with my tuned Turbo vs. my colleague’s stock Turbo S at our back road that the tune Turbo was ahead 11 times. Though I don't know anything about tune for the Turbo S, but if the engine and now the turbo is the same, any software mapping OEM or aftermarket would be extracting from the same engine setup, so what would be the advantage of the Turbo S?

 

Lets think for a minute, I would say that at least 50% maybe a lot more of these drivers will not touch the performance side of it, as they will be happy with 500 ponnies, so they will get the more HP they can get, hence the S.

Now knowing this, and knowing that a tune will give me at least 80HP, then the S wouldn't mean much unless you will always want to have the more exclusive car, then those will be the buyers.

 

Good point. I agree with you

 

Im interested in the GIAC tune for a turbo s. What kind of performance or power gains can I expect with the tune?

 

Great work! Kudos to you for pushing the limits especially with the limited parts/resources available out there for this platform. You earned that power!

I am in the market for a custom tune, so I have to ask. How happy are you with you with your custom tune?
