Going back to the question of issues other people have had, the main ones seem to be problems with back-pressure and over-boosting, resulting in broken rockers and wrecked turbos for the most part. Only way to solve that is either drive accordingly or to free up flow on the exhaust side - so you NEED boost and emp gauges. That way you can just drive with an eye on the emps and boost and back off when they get excessive, or adjust the turbo as necessary. Or you just fit a big enough turbo that it's no longer an issue, could port the exhaust manifold if the turbo isn't enough by itself.
Mine was running an estimated 140/240 in it's last state of tune, it was still going strong after 30k of hard abuse. However, the turbo was pretty well-worn and the valve train was beginning to sound slightly noisy. Causes: turbo too small; all of the red line; a few track sessions; 500 miles of mountain passes; the nurburgring; etc, etc. Not bad really, i thought.
Id agree with all of the above
So basically just run as free of an exhaust as you can get a hold of, and check over everything more often
Thats good! Especially due to the type of miles youve done
