Is the tune the same for all of your gt4s? Or does the customer load a base (OTS) tune, then send in data logs and receive individualized revisions from your in house tuner?
I am also interested in running this with the oem PSE. Can you pm me some pricing info.
Already been looking at this for mine once it's run in, just need to get it shipped to uk and fitted. But looking at the dyno charts it looks great and just what the car needs
John, these gains are awesome. What influence does the Fabspeed exhaust have for those that want to stick with the stock PSE?
And do you have any numbers on weight savings of the headers and exhaust versus stock?
Why thank you! We certainly do our best In regards to the the entire package but with the PSE we unfortunately do not have a dyno graph of that exact setup. However, here are dynographs of our Race Headers and Sport Headers on an otherwise factory GT4, and then with the additional of our Valvetronic Exhaust system on both.
In regards to weight savings our Race Headers save 10lbs, our Sport Headers save 6lbs, and our Valvetronic Exhaust System saves 5lbs.

Subscribed for future updates.
Thank you kindly! Please give me a ring or PM if you are interested in anything or would like to inside scoop on some projects in the works haha.

Catless Race Headers will set a check engine light, it is only a matter of time. However, we can make a custom protune via your Cobb Accessport to eliminate this CEL and at the same time give you quite a jump in power.
In regards to the IPD plenum/TB package, you have about a 50/50 chance of getting a CEL for MAF codes as the ECU tends to take a bit to adjust to the larger throttle body on the 981 platform. This can be resolved immediately by a throttle body calibration via the Porsche Piwiz scan tool.

Hello Matt! I'll shoot you over a PM momentarily, and will be sure to get you set up with the performance you are looking for.
The tunes are not all the same and are as you described via datalogging. For our custom protunes we will send you one of our own files optimized for your specific modification list for you to use to run a few datalogs. You then send those unique datalogs to us and we use them to tweak that map to maximize your potential performance.

Just DO IT!
I thought exhaust and headers with tune should be getting 400whp?
For me this is "the package", the ultimate engine mods for the GT4, nothing more is needed. Then suspension components as per orthojoe's post. Then suspension setup and corner balancing.
Kicking myself a little for not speccing the Clubsport package
And a tune haha. Those dynographs are simply exhaust upgrades, nothing more.

Thank you for the kind words, we are certainly doing our best to get this car to where it should have been to help put a hurting on some GT3s Suspension setup is certainly a must as it tends to push a bit on track in factory configuration.
As we all know this car also comes with gearing that is a bit too long...stay tuned on that one *hint hint*
Amazing stuff with just bolt-ons. This is obviously how the car should have come from the factory, had it not been purposefully held back.
One question, though--any concerns about doing multiple dyno runs on a car with only 250 miles on the clock? Meanwhile, everyone else is babying their cars with strict break-in restrictions...
