Sorry all, I'm not too active on the forums!
I'm running 14psi to get 400bhp and not as far as I'm aware but I don't know too much about engines etc if I'm honest. As far as I'm aware, the engine seems fine and Mike has done all sorts of tests so he tells me but couldn't tell you what those are as I'm not sure either. Turbo isn't appearing to be pulling oil. Car runs absolutely fine, no oil leaks and not smoking at all so it's very odd but also very frustrating!
No worries, I could write quite a lengthy review on it but it's just getting the time to do it to be honest and would take me a bit of time to gather all of the information as it back dates to when I initially blew it up in September 2019! It is mad that the car has been with TD for a total of 16 months agreed, it's been very frustrating to say the least and of course wasting tax and insurance money whilst it's not been with me... Gutted it drinks so much oil, it's not fun having to check it all of the time and having to top it up so frequently. For example a trip to the Lake District used 800ml of oil to get there and a further 800ml to get back (300 miles each way). So just shy of 3ml per mile... seem to be using more oil than F1 cars or fighter jets...
I wasn't originally running 290bhp, I went from a normal blown NA to full forged & turbo'd 400bhp and it's been problematic ever since in that aspect. Runs fine though, so I try to ignore that it uses so much oil (other than having to check it every day) and try to enjoy it for what it is, as it's pretty fun otherwise...
