I liked how it drove except for the surge before 4000 RPM in high gears, which stopped me getting one for my own engine.
I've heard the failures are caused by the stock oil lines not being adequate enough. I may have to contact FP and see what they suggest.

I hope they fix this reliability issue since it is a very good turbo.

Trying to contact FP now about the concerns I've went ahead and purchased the upgraded oil line from them. I'll ask them to cancel if it this is not the issue.

I'm posting a log of an up hill run (on ramp) in 3rd gear to show how even a little timing can cause big knock lol! I did get some timing added back into the lower ranges as i expected but I'm slightly disappointed i couldn't add much more on the top end.

Still a work in progress btw for all those benchmark warriors out there.

From 7000 miles away I can hear the engine begging you for octane!

Thats the turbo boost correction since i'm using load based boost control. It tells you what cell its in on the turbo boost correction table.

The VIII's are able to run more timing than the IX's

Perhaps that is generally true but this car definitely will not at least not with this fuel.

Do you know what failed on the turbo?

Its all good despite the cars lack of timing its still making good power compared to stock. The lag is there but not really as dramatic as i was expecting

how you get 8* timing at peak 23 psi? The best I could do on my 05 is 4-5* at 23.5-24 psi peak boost and gradually increasing to 13* at 7000+ RPM with boost tapped to 19.9-20 psi (yes! for some reason my car hold boost with the MBC) before it starts knocking. This is on 91 oct as well.

To the OP, it looks like the red is holding more boost up top than the stock turbo and that may causing 5-9 knock count starting from 6500. Maybe lower boost a little bit will help get rid of that in order for you to bump up some timings.
