This is another mod Nissan doesn't want you doing to your R35 GTR.

lol it can tell the dealer if it has been engaged? crazy. then whats the point of the damn thing?

The GTR has a black box (like the ones on airplanes) and it records speeds, rpms, everything. And on the Jap version (dunno about the USDM) when you start to drive it hard (like on a course) it will ask if you want to engage "Circuit Mode." If you choose yes then the warranty is automatically voided.

Top Secrets GTR only has an exhaust and Suspension. According to them, surprisingly the exhaust didnt throw a code, but just about everything does.

The deal with the warranty is also why JUN Auto hasnt been doing anything with the GTR.
