    I would go with head gasket.... Why do you say a bad tune? It's holding 24PSi so the map can't be that bad?

    as above defo not HG
    no oil water loss or mixing
    leakdown OK
    preasure test OK
    bad tune cos no paperwork or anything to say its got the right files
    and only 293bhp on the RR way to low for the upgrades
    so looking like it needs a big turbo file and the AFR's and timeing fine tuneing

    holding the psi as its got a EBC on there
