Not really, although other than thinking about the issue in the back of my mind I haven't done anything or changed anything as yet.

The car drives fine but had the small stumbles between 2-3k rpm. I thought that the engine bay may have been hotter than normal but logs show that it is normal. I put in a lower temp thermostat just in case though but it didn't really make much of a difference. The cooler weather now seems to help with reducing the stumble too.

Ideas that I may look at over the next month or two.... Remove the turbo and inspect to ensure there are no leaks on the up-pipe. Also check the compressor housing to cartridge seal. Put the car on a dyno and check AFRs and see if any noises can be heard beside car when WOT.

I may also bite the bullet and swap rails and go to a parallel fuel line set-up whilst I am doing it.

Cheers

Dyno check up sounds like the go.

Bye bye betty blue. Hello F6.

Sounds like what I just went through. S-Technic diagnosed and fixed it. Maybe give them a call and see what they did to correct the issue. Was injector/maf related btw.

Thanks for the suggestion and help. I will try to make some time.

did you ever get this sorted? I have mine running with this same turbo now. Seems pretty good so far, although im not pushing it super hard. Just 260kw atw is plenty for me.
