Thanks, I hadn't seen that. And I didn't realize that Skandalis' run was verified - well done!

Just makes me wonder why no other tuner has been able to do this. You MUST have to seriously increase the boost or something to come up with this acceleration. Hard to believe that it won't affect the longevity of the engine but that's just pure speculation. The other offerings which get you into the 6-7s range for 60-130 cost far more and involve a lot more hardware changes. The truth is out there....

 

Good point on the boost levels The Bogg! I recall Skandalis saying something in an earlier post that his APR tune is running only stock boost levels so something doesnt add up? Where all that 865nm of torque came from i'd like to know.

Matthew can APR provide us some info on how much boost they have screwing into the engine? They surely must know. APR should have no reason to be secretive on this point.

BTW, Is the OP still out there?

 

Guys,in order to make thinks clear about my oil issue,The problem is that I have in my shop Mobil 1 0/40 engine oil from TWO different importers here...same oil,same bottles...Oil 1 makes start up noise while oil 2 does not.when i filled the engine with oil 1 and had the noise,i tried to see what was going on...But these bottles were from a different importer than the one I use for years in all my cars...So i put oil 2 from my previous oil importer...And the noise dissareared...it is obvious that there is something wrong with that oil,and that explains the price difference between two importers...The reason i sent sample to lab is to verify that this is not Mobil 1 oil and caused the noise.Once again,same oil,same viscocity the one makes noise while the other doesnt...there is nothing wrong with my engine...noise dissapeared and i still use Mobil 1 0/40 oil.but in order to protect my engine i replaced noisy oil at 1300miles...(I could not stand the start up noise after 2-3 days of sitting...)

 

For those who wanted to know which dyno APR used for their graph, I have inquired diurectly with APR and will add this information as soon as I have it.

 

I say only what i read on boost gauge...it reads 1,0bar all the times,whether sport mode is off or on...there is no overboost arrow in sport mode with APR tune...However throttle is more aggresive in sport mode...and 100-200 times have 0,6 to 0,7 difference...

 

Skandalis, There must be something wrong with your guage because I drove a stock 997TT yesterday and with full throttle it was achieving atleast 14-15 psi at least. I was not on it for very long as I was just getting onto the high as we had just put H&R springs in it. I also emailed a local customer who has APR software via email to find out what pressure levels he is getting as well.

As for reliability of the car with APR programming goes, I think its common knowledge that once you increase the power of any car the stock clutch will need to be replaced at some point. APR does sell clutch upgrades for every car they offer software upgrades for to answer speed21's question about selling them with packages.

The reason why they don't package the software together is because there are several different types of clutches for every car depending on what the intended use and driving habits

 

Sorry this just in from one of my local clients, Keep this in mind that this is not 100% accurate, just something my local client noticed while holding on to dear life and trying to remain focused on the road ahead of him lol that his turbo is atleast putting out about 18-20 psi. Again something he is just glancing at for a second while trying to keep his eyes mainly on the road.

 

Having an APR tune with FVD exhaust I have posted in the past about the APR flash. My boost gauge constantly maintains 1.0 bar with or without sport mode. The throttle response is increased in sport mode. I am unable to DYNO my car here in Charleston,SC due to the AWD. I noticed my clutch slipping, only on aggressive acceleration, as soon as I installed the tune. With race gas, forget it, the OEM clutch will not handle the torque. I am waiting to have a SACHS 2.5 installed as soon as it arrives from AWE. I have about 10k on the car since the tune. 500 miles after the tune the only issue was an electrical short in a front end wiring harness which affected the whole electrical system. I ended up having to disconnect the battery to open the doors and shut the horn off. A tow to the dealer and new harness later the only issue has been the amazing torque requiring a clutch upgrade. PITA. However, that being said. The electrical issue was covered under warranty by the Porsche dealer and the ECU upgrade was not detected.

How many miles were on the car when you bought it?

How many miles were on the car when you installed the software?

How many miles are on the car now?

If your clutch was slipping immediately after you installed the software then this leads me to believe you purchased the car used with some miles on it.

The TT I drove last week which was stock by the way, I could already feel his clutch slipping driving in traffic, back up and starting forward from dead stand still. This car has 5000 miles on it but he is the second owner.

You can easily burn out the stock clutch by constantly over revving the the rpms while starting from a dead stand still trying to find the engagement point. Once it gets heated up real good a couple times its lost its grip and never fully returns back to its gripping form. I think Porsche should have put a slightly strong disc from the beginning.

 

Bought used from a NASCAR higher up with 4500 miles on it. Traded my M6 convert. Never any clutch issues. Installed APR with about 7500 miles on it. Slipped only during WOT between 2-3 and 3-4. With race fuel it slips 2-3 thru 5 during aggressive acceleration. Never during daily driving conditions.

 

there is nothing wrong with my boost meter...i do not know if APR software has locked the meter to show up to 1bar because i havent logged boost pressure to see actual values...It shows 1bar all the time...

geez that seemed fast. And I'm just sitting at the computer!

 

Please tell me you weren't driving and recording at the same time!

 

Am i reading this right that since installing the APR tune your clutch slipped straight away and you have put up with that for 10,000miles? Why?

The boost gauge being locked at 1 bar sounds like APR hasnt done its homework very well there......not a great sign to be honest.

Skandalis it doesnt gel at all saying there nothing is wrong with your boost meter when it only shows 1 bar all the time and the car is producing way more than that. Even in stock tune it should show 1.2 on gauge at WOT in Sports C mode.

Seems to be a common problem there for APR. Matthew from GMP says APR tune makes 14 to 15Lbs boost at least. More homework required on such a basic dash function...hmmm not a very good sign.....so what else has been missed?

I was thinking much the same. Fancy...

 

On a stock 997TT boost reaches 0,8bar...And at over 0,9bar and rarely 1,0bar...APR GREECE stated clearly that boost will be always 1,0bar and that is the way it is,at least to my car and 11 others here with the same software...We have 12 cars with APR flash,all tiptronic...One was manual and when flashed it burned the clutch...
P.S. Yes i was driving and filming...thats why mobile phone slipped away at startup...
