I've taken it off now. Working through overdue service items, so with a bit of luck will get my improved performance that way for the time being
. Done all the filters and oil, moving onto viton seals for the leaky intercooler next. Enjoying it so far though, gives me an opportunity to get to know the vehicle.
Holding onto the box for the time being while I work out the next step.
Not been able to identify the MAF yet due to the weird bolts. Will give this a look in due course.
