Running 12psi. All fully tuned.
Full exhaust, fmic, NEW oxygen sensor (for best fuel economy), pod filter, sitc, safc, ebc etc etc.
Get over 420km per tank (hitting resevre), with 160awkw.
Great pick up at 5000rpm, no splutter for me - a nice safe tune, rarely do I let it stay at 12psi....... (heat factor = dead turbo).
Got a spare turb' sitting on the shelf.......
