Congrats!! Gun metallic is my favorite color for the R35. As as you said in your prev. post, a Cobb alone wont get you into the 10's. Those who have run the basic etune on cobb with a custom map loaded along with a midpipe have broken into the 10's. A cobb alone with midpipe will get you in the high 500 hp level. Add a catback, downpipes, intakes and fuel injectors and you could be close to 700. Once you start modding, the injectors and intake are the bottleneck because the MAF voltage gets maxed out around 5V, so theyll need to be upgraded if you want to run 17+ psi.
