Hi all,
Blasting down M25 this morning,well late lol,overtook some cars at high speed,boost guage hit 18psi(although it's only mapped to 16psi),next time I floored it the usually razor sharp throttle response had gone and it would only hit 8psi which I'm guessing is base.
I've done 100 miles since and it hasn't changed,no warning lights or messages though,fuel consumption fine,starting on the button and idling perfectly but 8psi boost
Been under the bonnet briefly,no obvious pipes off or split-tcv,one way valves and maf all new in the last 2 months,so haven't got a clue tbh
Any ideas gratefully received(btw V70 T5 2001)
TIA
