[QUOTE="FaSSt9602, post: 602340, member: 1872"] Virtually no engine is truly reliable at those levels...you are tempting fate at anything over stock really, but I have thought all along that it was only going to take some time with tuning before the fears of 550hp tops on a stock bottom end were put to rest. I do think that whatever single turbo they have on there helped the cause. The stock turbo works AWESOME for what it was designed to do, but when turned up I think it is too much, too low in the RPM's...stock turbo trucks make peak torque REALLY low, this one was somewhere around 2500rpms.
