Randy Probst driving APR 997 Turbo

I had a APR tune on my 996 Turbo and I must admit it was great. You could switch between race/street/valet easily. It had more power than GIAC.
There is a downside. They promised that they were going to create other higher horsepower tuning packages and they never did. Ultimately they abandoned the 996 turbos.
If you are just looking for a tune and are positive you will go no further than it is a great option. If not look at other packages and tuners committed to the platform.

I spoke to them about trying to do the VGT turbos to retro-fit on the 996 Turbo but they said that the resources they would have to use vs. the number of units that may be able to sell just did not make sense. Alone the VTG turbos are expensive and the prices of the 996TT's have dropped.
There are other high horsepower options but you lose so much low-end power. For most people that get in the 996TT APR programming, the swift kick you get from their low-end torque is all most are looking for. Big top end power, yeah, there is other stuff out there.

What kind of power would you make on a 996 TT with K24's and exhaust?
Also, is there any failsafe for these switchable modes? What if you put it on race gas tune but only have 93 octane? Who are your dealers?
How much for this programming?

hc, are you thinking of trying APR?

Like 996TTR pointed out, APR has tuning for stock parts. I do not think they have a tune for the k24's.
You will need to make sure you have the correct fuel in the vehicle. The car is smart enough to retard the timing a bit so if you cannot find the right fuel, you can run it and it does drive but we recommend putting it into stock mode and staying out of the boost.
As for dealers, we are the APR dealer in the Charlotte Area and would be happy to get you setup. The standard pricing is $2499 for the 996TT. Mention this post and I will get you taken care of.

APR has taken your cruise control buttons and utilized them for this function. Your cruise control will continue to function as normal, but will give you the ability to scroll through the programs you have purchased on your APR chipped ECU. The procedure is simple and involves only two steps.
When I searched for California dealers, I found a bunch of strange names and not any well known California Porsche tuners. Is APR working on getting some "big" names (other than you ) on the roster?

I was, but since K24's aren't considered as stock even though they come on GT2's and Turbo S's then I guess I'm out of luck. I also am not interested in all low end power, I like a more useable powerband on the track, one where hp increases almost to redline which is what mine does now. The only thing I was considering was getting more power from the K24's, but that does'nt seem like an option.
But I've seen too many cars claiming way over 600 hp that didn't seem any faster than mine so I'm not going to take a chance and mess up a sure thing. Not interested in hybrids. Just want to get the most from the K24's.

Thanks for taking the time to answer. This solution seems a lot better than GIAC's flash loader.

Everything sounds positive, and I know first-hand that APR has a great track record with Audi, but if you are going to claim it is the best, you should back it up with some head-to-head or back-to-back testing. I do realize the money-back guarantee goes a long way. Testing goes further.
I have visited with the engineering guys at APR and see the lengths of testing they go through. They have different departments within the company that are resposible for each operation of the development. They approach their calibrations with a philosophy that actually has them receiving purchase orders from car manufacturers. VW was using their fuel pumps to win the 24 hours nurburgring in the Sciroccos. These guys are putting Porsche cars on the track with professional drivers and driving all day long at wide open throttle to prove their product is the best.
I can offer a money back guarantee that if you dont think its superior, no problem, here is your money back. Drive it and see. Drag race it and see, dyno it and see. Its up to you. Everyone that has gotten it, loves the linear power band, the incredible torque curve and the ease of toggling back and forth between programs.

Here are a pair of dyno graphs. Each graph is at the rear wheels with the only difference being the octane fuel in the tank and the APR program selected. This is done through the cruise so the APR programming is native to the Bosch ECU and operates seamlessly within the ECU.
623hp and 681lb ft at the rear wheels is the maximum power output of the 911 Turbo. Using only a 10% drivetrain loss equates to 685hp and 749 lb ft of torque at the engine vs Porsche’s OEM numbers at the engine.
93 Octane
100 Octane
