Guys I bought a car that originally had a GIAC tune. She currently has headers, cats and exhaust, but I'm not sure if the dealer flashed the ECU to stock for CPO reasons. Are there any signs that could help me figure this out without going to a shop?
Does the GIAC still allow for sport mode to change overboost?
She feels quick but not 600hp quick.

Any help would be appreciated.

 

I have a softronic tune that raised the boost in sport mode above the 17psi max that is shown on the readout gauge.

I would put the boost up on the display and go do some wide open pulls. In sport mode, when you go over the 17 PSI that the gauge will read, you will see a little arrow pointing up. Meaning you are over the 17 PSI max.

That would be a good indicator in my opinion.

GIAC tune will act the same as mentioned above.

 

Good question. What if you don't have sports chrono?

 

^^^now that's a good question!?!


Actually I recall Champion stating if I wanted to go with their performance package (GIAC), I needed to order my car with Sport Chrono because its the only way to get the "over boost" and this is where the GIAC tune comes into play....

 

Hello, More than likely the dealer left the flash installed but it is set on stock instead of pump. That is exactly what happened when I bought mine. Get with Mike at AWE and he can get you the handheld flashloader (150.00) .
You than plug it in to the port right under the steering wheel, turn on the key and push read on the flashloader and it will light up the stock or the pump light. If it lights up the stock light that means that the previous owner turned the flash off before selling the car. If that is the case, push the pump button and it should light up . Get in and find out what all the excitement is all about.

 

NOTE to the OP: Without upgraded IC's GIAC would have your tune at 565HP/550TQ (max)

 

Contact Giac and supply them with your vin. number and they can tell what flash was installed and when.

 

^^^This is very true. Although the OP still won't know if his car got set back to "stock" without the handheld control to verify its current setting.

 

I'd like to see someone from Champion chime in here...I bought an 08 turbo with the GIAC tune-(CPO)-no sports chrono-lots of mods-told me it was 700hp...? Without being able to compare any before and after driving I'd be curious if the tune is there or not. Maybe its called trust?

 

If you have a Durametric, datalog rpm, load, timing, lambda, and boost then send it to me. I can compare it to some of my files.

 

Have you gotten your Europipe yet?

 

With headers, cats and etc., actually with pretty much any modifications the dealer can not CPO the car. If they said it is CPO, I hope you have official paperwork, not that it may mean anything as Porsche will try to get out of the the warranty due to the modifications. Again, subject to your dealer working with you and being nice to you.

As for the tune, others have chimed in as to what to do.

Keep us posted.

Cheers.

 

It's quite a bit of work to get 700hp out of these engines. Talk to Champion to see what the modifications are to your car and what power range you have and if it is Champion you may want to have it checked out to make sure all is still up to spec as with that kind of power you want to make sure that everything is set correctly. As per my last post, I will be very hard pressed to believe that with the modifications your car is CPO'd.

Cheers.

 

I've seen the arrow... And I've seen boost near 18psi. I guess the tune is active and I'm just jaded.
I had reached out to GIAC and they confirmed the car was tuned in 07, I just "assumed" the dealer would flash to stock for CPO, since they went as far as remove the clear bra to adhere to code.
