In case you are wondering:
Mr. Cardwell,
We do not have software available for the 04 GT3's just yet. We are expecting to have a few different kits out for those later on this summer, so, definitely check back with us. Thank you for your interest.

Phil - I doubt that a chip would do much for a GT3. The Cup car has only 9 HP more and that's due to the less restrictive exhaust system (race cats only no mufflers). Since the 993 the factory software has gotten much better and ECU tweaks don't seem to buy very much. Turbos are another matter if you are willing to take a risk with extra boost. I noticed that the ECU programming is now regionalized. I guess to compensate for the lack of 93 (or better) octane in CA for example. IN the old days the factory chip was the same everywhere and settings were conservative to allow for lower grade fuel in certain parts of the world. I'm told that this is no longer the case which makes it hard for the aftermarket guys to improve things.

Having said that, I agree with you on the rest. There is really very little, if anything, that can be done to improve the ECU on the GT3 or any other normally aspirated engine. I suggest we all explore the limits of the factory's mapping before we even go out and look for more.
