Bottom line is I don't think the rev limit (stock or otherwise) is a huge deal in terms of warranty coverage within certain allowances. Ask Dinan, ESS, Evolve, BPM how many warranty issues they've encountered with customers with something not being covered.
The stock limiter is on my car and coding recorded a top RPM of 8600. It happens mostly on down shifts during very aggressive driving. Time stamp confirmed it happened before I bought it.
