I've been told by several people that race on a regular basis that sustained high RPMs is what kills it...they said don't take it above 6500 or so. The car doesn't really make any power up there anyway. The tunes that increase the rev limiter are a good way to grenade the motor... not the tune itself... the fact that now you can rev the motor higher than it was designed for....
Problem is that when your racing, your not always looking at the Tach... bouncing off the rev limiter lets you know that your at the upper limit only now with the tune, your well in the danger zone by the time it's bouncing the rev limiter. I would asume that most people that track their cars also have some kind of tune on them too.
BTW I have 120K on my car and have beaten the crap out of it since I bought it at 44K... so far, it's been one of the most reliable cars I've owned
