just on the hot side exit of the turbo at the 90deg bend
it was a bloody band clamp ,it had locked up on me and i thought it was really tight so i left it be
turns out it wasnt and was leaking pretty bad
which may explain why when we went from 14psi to 18 psi it would only go up by 2-4kws poor bloody turbo was working its ass of to make 18
it does drive different now with the boost fixed
way more responsive lol
