In the market for a turbo coupe upgrade , currently have a 4s cab with pse

1) test drove a 2015 TTS coupe , very fast , felt it had great acceleration, no lag and sound was ok. Ride was great , probably due to PDCC compared back to back with a 2019 s cab
2) test drove a 2017 tt cab and a 2015 tt cab , both felt good but not as good as 2015 tts in terms of that acceleration rush , little lag where I could feel when turbos kicked in and ride little bumpy on avg roads 3) test drove a 2017 turbo S and it felt fast similar to 15 turbo s , but difference was sound and had that explosive acceleration rush just like the 15 tts . TT and Tts May be same 0 to 60 but accelaration from slow speed, stop light was more intense in the TTs. The turbo whooshes etc were more noticeable in the 2017 tts compared to all other turbos I drove , the sound was very satisfying . I don’t like test drives much due to sales pressure etc but that is the only way to check these cars out . I am writing here because 911 turbo owners with more real experience will be able to help give feedback on my observations before I decide

Thank you for your time

 

If performance is on top of the list, get a 2017 or later TTS. Bigger Turbos for the win.

 

Agree

 

I don't know if it's my imagination or not, but it seems my 991.2 TTS is faster than the 991.1 TTS I had

 

Much faster.

 

May be , I felt tts had more pull than TT . Elliot, how about the sound difference between .1 tts and .2 tts and is sound better in sport plus ? Which I did not try

 

not much difference is sound, at least to my ears

 

Buy the Cobb AP for the TT. The HP gain will get you almost to the TTS level. The torque increase will solve any turbo lag you might be noticing. Add a Kline exhaust and you will sound sweet plus some more ponies.

 

2014-2016 991.1TT/S = smaller turbos with quicker spool but less top in pull (the low end torque and pull makes it feel very quick off line / corners)

2017-2019 991.2 TT/S = larger turbos and more over all hp. Slightly slow spool but bigger top in rush.

Sound ? Forget the stock exhaust sound and buy a Europipe and NEVER look back. (perfect fit / perfect sound)

More power from either = Cobb AP with an OTS stg.2 tune....991.2's will respond with more "gained" WHP.

 

Thanks for the feedback. Does the 991.1 tts std exhaust have pops, gurgles and overruns?

 

If you look at the actual acceleration numbers, the 991.2 TT is same as 991.1 TTS...it'd be hard to distinguish.

I had a 991.2 TT and really liked it- but after having PCCB in my GT3 I'd go with PCCB on a TTS, most likely.

 

Yes, it will, in Sport mode- I think maybe in Sport Plus it may go away? But who cares in that case because you're in assassination mode.

 

It does, but they’re subtle with the OE exhaust. The 991.1 cars will do this in Sport or Sport Plus mode. I think the 991.2 cars only do it in sport mode. If you really want to hear it, you need an aftermarket exhaust.

 

The other consideration is if you are interested in tuning, the .1 doesn't require ecu removal and modification to tune with Cobb while the .2 does.

 

That's why we're here! No need to remove the ECU for either, and it's plug and play no splicing or anything.
Just install, and enjoy the new added power!
