Yes I run a mocal oil cooler
Unfortunately, the t25 starts to spoil up at around 1.5-2k revs... Which normally is a good thing, with no lag, but maybe not for any kind of motorway run?
I was thinking 10psi was "low boost" haha - is this not the case? With a switch on the dash to go up to 14psi when it's needed
