The problem with this kind of boost is that over time rods will bend, specially if you have no idea what s going on in your engine, or put less octane in tank than required by the tune, every knock with that high boost at rpm can help deteriorating
then suddenly one you get a rich afr, misfires and knock all the time and car doesn t run a shit and you ll notice the compression in cilinders is gone
luckily you use e85 only and that helped, probably you avoided often going to redline too

Sorry to jump back but even at 8k the most i saw in my logs were 1.95bar absolute. Do I have a boost leak?
