Thats a shame at 30k. Mine's currently at 230k and has been pretty well "tuned up" since 100k. Did egr cooler and HPOP between 155k and 175k. Currently in shop with trans. issues, but never had heads off or any lower end trouble. Dunno.
Well I am looking forward to the better parts getting put in under warranty. Better blown under warranty then after. Soon after the heads then comes the injectors and a turbo for towing.
I think I got the bug. The Dyno didnt help.
