5EK82590 with a 550 file done by a reputable tuner. Just had it dynoed after rebuild. 917HP at the flywheel and 764 to the ground. I ran that tune for years on the stock turbo and manifold before the gasket started leaking and the head developed cracks.
During the rebuild I had a new 80mm turbo put on with a 1.45 A/R that now gets me around 42 lbs of boost versus the 25 or so I used to get. Well, my head gasket blew within two afters getting it back from the shop. Is this too much boost? What can I safely push before fire ringing the head?
