C2 Turbo

Hello Guys,

Just discovered my sport button few months ago and I LUV IT.

I am now wondering how much more fun is a tune vs the sport button?

The difference between the stock setting and sport is very noticeable and is it the same between the sport and the tune

Thanks

C2..... Brother I'm saddened that you just discovered the sport button...

The sport button with a tune rocks..

The car behaves the same with a tune but with more power. The turbo's spool faster and you have a lot more torque.

When the sport button is engaged it advances the timing just like stock. So I guess the answer is the the sport button with a tune is awesome..

+1. I was skeptical about tunes in general until I got a ride in Phillip's car earlier this year. As he said the car "wakes up" with a tune. I felt the stock car was a bit sluggish below 3K and tame above 5K (even in sports mode)

But a tune+exhaust is really all you need to unleash the beast in your car. It's more responsive, turbos spool earlier on the low end so you have more accessible power below 3K. and the turbos spool faster in general with a free flowing exhaust so you have much less turbo lag across the entire rev band. And in sports mode the turbos will maintain boost all the way to red line vs cutting of at 5K. Totally worth it IMO

when I completed my PPI the service tech told me to get a tune because "it wakes up the car like you wouldn't believe".

Agree exhaust and basic tune is all you need on a 997.1tt

With a tune the you will notice and even bigger change between the two settings. I actually prefer PASM stiff and sports mode off on the track, far too sensitive to throttle inputs.

How many people have tunes and a stock clutch? I have been told the stock clutch won't last long. I was told the same thing when I upgraded the turbos on my B5S4 but I never had a clutch issue.

Hah a good tune is like having a sport plus plus plus plus

Whose tune is viewed as best ? I realize that may be somewhat subjective.

Stock clutch here and in my old blue car, which dyno'd at 466 awhp, about 560 crank. Never slipped. I think 550-575 is about the limit if the stock unit. Just my experience, others can chime.

I know the Sport mode changes the throttle map to be more aggressive - I wasn't aware that it advanced timing?? Is that true?

eurotom

Not being sarcastic at all, but once the users on this forum determine which exhaust is the best you will have your answer

Plenty of threads on this topic, many good tunes each with good and bad feedback.

I have a 2 can Tubi exhaust on mine...

I have 65k miles on my stock clutch. 25k of those with the tune and exhaust. It is finally starting to slip in 4th and 5th with race gas at WOT.

Have to get that done soon. Possibly go to the 2.5 clutch or just another stock. Not sure yet..

It makes sense what TT says about max HP for the stock clutch.. Mine does not slip with pump gas. But it does with race gas (which may put it over the 575 hp mark)

While on the exhaust topic, so yeah what is the best exhaust for a 997.1 TT

Only1Buck

that would be a Tubi 2 can
