^^ Any info/pics on that? I ordered a GTM SC kit and looking to do something about that opening.

Brazilbro's GTM TT
That is Brazilbro's build thread, looks like they cut out the fangs and made a huge opening in the front for his setup.

Thats one way to do it. I wanna say that Blue did it different. He removed the black fins in the middle of the bumper.

Z1 sent it to the body shop and we had them cut until the intercooler was completely exposed. Call John @ Z1 for more details.

Because I have a 7AT we wanted to make sure everything was as cool as possible so thats the reason for cutting away so much of the front fascia. Pictures and dyno results are in the "my album" area.

Well early on in this thread I posted my opinion on the R6 tune. I have had the R8 tune for sometime now but just have not had enough seat time until recently to give any feedback.

Well here goes; The first thing I noticed was that the tip-in knock that I was experiencing was gone. The power is down a bit below 3K rpm and I presume it's because they removed timing down low to eliminate the tip-in knock.

There does seem to be more power in the mid to upper rpm range though like I said some of the initial down low the power is down from the R6 to the R8 tune.

Shifting is firmer particularly at moderate to full throttle compared to the R6 tune. I have noticed that the R8 tune is a bit more sensitive to throttle input and will sometimes shift too early with a slight let up of the throttle and then when you get back into the throttle there is a hesitation before gearing down and going. Now that I'm familiar with it I can somewhat control it.

As for the hot start that I was experiencing with the R6 it is still there with the R8 tune but is now happening more often. With the R6 tune it was once in a while, with the R8 tune it is more common whenever I am driving for an extended period of time and the engine is good and heat soaked, even on a day where the temps are in the 40's. It's like the motor is getting too much fuel on start up and it requires throttle to start or else it will just turn over and not start. Obviously to rich on start-up requiring throttle opening to get more air when ever the motor is good and hot.

So that's it in a nut shell, some improvements but not quite there yet. My preference would be to have the added power from the R8 tune with the drivability and smoothness of the R6 tune. Plus fix the hot start issue and I'll be 100% satisfied.
