  1. FUEL SMELL PROBLEM?

    Has anyone had the following issue before? Essentially when 1 or both windows are down I get a fuel smell after letting off throttle from a mid to hard pull, basically when boost pressure is released.
    Generally cruising around or if windows are up there's no smell at all.

    Only noticed since fitting a new turbo, everything else is more or less the same when i ran a hybrid and I had no fuel smell issues.

    Carried a smoke test with no leaks, doesnt really help as theres no smell on boost only when releasing boost.
