so your boost with APR reached 17 psi ???
Yes, this video was done after they completed writing the new software. It was since been fitted with an exhaust, headers, sport suspension from Koni, and BBS RSGT's. They make up the power from lower boost numbers with timing so they can achieve similar numbers from their competitors but with less work from the turbos.

thnx for you care ,,,
am just wana besure how boost i will reache with APR .. becouse i allready moded it in my car .. when i was stock my boost reach 14 psi ,, now when i put the APR tune it just become 15 psi !!!! so is it normal ?? or the tune is wrong ?? as well as i did not feel much power in my car .. so am afraid that maybe the tune is wrong .. thanks for your kind
waiting your answer
I can answer your question with more detail in an email if you want to email me @ mkrisel@gmpperformance.com
Depending on internal temperatures and weather conditions boost pressure and fluctuate within 1-2psi. I have the APR Software in both my 2.0Turbo VW cars and I always achieve a little more boost in the mornings going to work then I do on my way home but either way it's still a significant change from stock. So you currently have APR Software is what your saying?
It's possible your car is in the stock program or that the security option is activated which is when all your programs are locked and the car is in stock program.

YSfg35- I received your email and working on your reply.
Meaker, I can only speak for GMP. Locally between 5 and 10 cars locally and I have done atleast 10 or so internationally. We are not the only APR Dealer though so I'm sure there are many more. We are one of only 2 or 3 sponsors on here that are actual APR dealers versus atleast 10-20 sponsors on here are GIAC dealers. Most APR dealers are on the VW and Audi specific forums or they are strictly local service.

We also offer a 30 day money back promise, if your not satisfied you can come back in get flashed completely back to stock and we will refund 100%. The software purchase comes with stock program, 93 or 91 performance program, 100 octane program, Valet, Anti theft, and security

I rich tune is more likely to spit flames from the exhaust, which will add access heat to the rear bumper causing it to brown in color. Most times the discoloration can be buffed out, but it's no different than race cars spitting flames.
This is assuming that he meant this, since it's really the only legit explanation I can think of.
However there are plenty of stock vehicles that can spit flames, especially when the cats are altered or removed. So while this is possible, a little more detail would be helpful.

Yes I agree a little detail would be very helpful, especially since I've never seen this complaint before from a 997 Turbo GIAC tune. It's somewhat of a strange reason for dropping 2-3k for another tune.
Guys who are asking about the boost reading:
Do NOT rely on the dashboard reading of boost! The 997 Turbo is PROGRAMMED to read max values of 1 bar (14 psi) in Normal and 1.2 bar (17.4 psi) in Sport mode, regardless of the true boost values. The max numbers will be the same before and after the tune. What you WILL see is that the car reaches that max numbers much faster and much easier.
As far as true boost, someone in-the-know
corrects me if I am wrong, but I wouldn't be surprised to see max boost with the 997 Turbo in the range of 1.5 bar/21 psi in Sport mode, or more. I've seen numbers from GT2 tune (sorry didn't think to copy URL), same engine as our Turbo's, that I recall were around 1.6-1.7 bar. (Have never seen 1.8.)As far as whether some company could find a way to increase torque/power without as much increase in boost as others? I don't think so!
Again someone please correct me as needed, but there are only so much power to be gained from alteration of timing and AFR, the big gain is from boost. If you want more power, you are going to see big boost, no?? Isn't this why it's so much easier to gain power with a Turbo engine, versus NA?

HC, thanks as always. I was wondering myself, if a little mineral spirit wouldn't help?

Also I am curious as to how much boost the chipped cars are running.

Can,
You are spot on the boost readings. You are also correct in regards to power increases being limited with just timing and AFR changes. My EVOMS tune is supposed to run 18 -19 psi in non sport mode. That is the beauty of a turbo motor. As long as you stay within safe limits, you can increase boost and get some great power increases. I am weary of overboosting the 997tt motor simply because of the cost to replace it, just in case something goes KABOOM. I know our power plants can handle much more, but better to play it safe IMO. I have done many overboosted imports in the past and they can make some stupid power by increasing boost. There is nothing like forced induction!

FYI I don't mean to call you out, It's just that I would like to know what PSI and at which RPM Range they are using it to make their power so I can ask APR about it and see. We haven't had the opportunity to install a boost guage on one of these cars yet so if you have I really would like to know what the results were. Thanks.

So your saying that APR reasoning behind how they are making their software is false? If so have you tried the APR software prior to your purchase of the GIAC software and tested it to see how much PSI they were using and at what RPM's they were using it at?
