Almost 75k on the same set of turbo's. I think it's luck of the draw a lot of times, so run'um hard and have fun. Just remember, if you play, eventually you pay.
I thought about over-driving them in the midrange a little past max boost/efficiency range, but I'll wait until I get downpipes hopefully will be in the next 2 weeks
