Well gentlemen, I have taken your advice and I am getting my ECU flash today by a GIAC dealer I found here locally. I am very excited about it. I will provide you with some feedback this evening.

 

Keep that radar detector plugged in!

 

sweet. what kind of power increase does GIAC claim?
also how much is the flash, i should have done it.

GIAC claims 15-20 hp and 20 lb/ft torque. The flash was $995. I will provide more feedback this evening once I have a chance to really play with it. Hey, BobbySpeed, what should I be looking for in results of the flash. (I drove it back to work and there was no mind blowing difference, but that was only a 5 min drive in traffic) What should I notice?

 

The first thing you should have noticed is that your ride was too short.

Have you upgraded your exhaust and switched to BMC filters? You need a way to get more air in and out.

Throttle response should have improved with the flash, but without really good flow it's hard to notice any significant change.

Are you running GOOD 93 octane gas? Just because it says Premium doesn't mean it's 93 octane, or that it's good quality. What is the Ethanol content?

Remember, it's a very heavy vehicle, and it takes a lot to feel a big difference- you are on the right track!

 

Unfortunately, no other mods yet. As for the fuel, I can only assume it is 93 Octane, because that's what the pump said. What brand do you recommend?

 

I am in the NY metro area and run Sunoco Ultra in my cars. Mobil Premium (93) is my second choice.

 

Unfortunately, neither of those is very accessible in the Jacksonville, Fl. We typically have Amoco, Shell, and Gate Petroleum (garbage).

I did have a chace to test the new performance and what I see is much more power off the line. I imagine it would be even more noticeable with some complimentary mods, but...

Overall, I am satisfied, but since I am not a hard core tuner; I am sure I could have spent that $995 on something else and been just as content.

 

Run with the Amoco Premium.
Put in a set of BMC air filters to improve breathing, and look at replacing those extra catalytic converters with a pair of bypass pipes and a muffler- Cargraphic or Fabspeed. Once you've improved the flow you will have a better breathing Cayenne that will be better suited to take advanyage of your re-mapped ECU. Then, you will be very pleased.

 

where I can get BMC filters?

I am getting the pipes and after ecu...

 

I got a great price on mine from Jay at Brandywine.

 

you mean http://brandywine.porschedealer.com/ ?

 

I would go a step further than getting new BMC filters - if you want a real improvement in airflow in then get a set of EVO- Flow intakes for your Cayenne S -$595 well spent! Plus about the same for cat bypass pipes.

 

Saw that on your site man!! looks great..

I might do that mod then , just do cat bypass.. like you I'm hesitant to do exhaust ... then i will see which flash I'm getting, i'm still upset about

not getting any credit from GIAC from my previous flash .. i'll try upsolute,LOL then we can have a giac vs. upsolute debate on Cayenne forum

 

You can get BMC filters from Carnewal-europe
