Don't increase the boost too high or the standard ecu will cut in to protect the engine. You need to buy a sports ECU or an FCD (fuel cut defender) to get around this. You should also fit a decent boost gauge so you know what boost you are running.
To be honest, I thought the standard boost was less than that. Maybe a previous owner has already fitted a boost controller?
hi just fitted my boost controler standad boost is 0.8/0.9 running mine at 1.3bar any more will shut the fuel off from the ecu as it thinks it has a turbo problem hope this helps......
