Its posted here in the 991 section. Sorry if I did not add it earlier. The dyno will be done, but is the least thing to bench mark as you cannot gauge the driveability improvement with 1 single gear pull. Will show you what you ask for though!

 

How does the dealer not detect it? On any other car I know if you do a tune the car's computer will track it.

 

On any other car is a pretty general statement. This would boil down to whos ECU Tune, process, and tools used. Since this is a "TCU" flash flashing small bytes of data to the central convenience module as engineered by these former Porsche related employees, you can flash back the stock data or the modified data. Having a Porsche PIWIS myself, if you take your car to a dealer, whether a 997 Turbo with a full DME ECU flash or this 991 with a TCU Auto Flash, there is nothing that pops up and says "warning warning" or "Warranty Void". The dealer technicians go through the PIWIS modules to work with the related issues the car was brought in for. If a ECU needs to be reprogrammed, you simply go into the DME Programming section and it writes the latest firmware to your car.

So for each time you go to the dealer for a oil change, fix a rattle, have your sunroof checked out, or a transmission noise there is nothing to look for. If you take your car out to a track day, run 100 laps, blow it up, insist the dealer replace everything or buy back the car in a benevolent way (lol), then they will probably have their Porsche engineers like any manf dig very deep to find the root cause.

I was up at the local dealer with my 991 Turbo talking about mods and warranty. He said, "we try to help every car that comes in. Just cause it has parts on it, does not mean the warranty is void. We have fixed cars with full cages, track tires, and turbo upgrades under warranty. We simply submit it to Porsche and they tell us where it lies"

 

Any word on the tune taking care of the cel caused by race headers?

 

Not yet, waiting for them to make a trip out here for testing. Then will have that worked on.
