If anyone can help i went out last night was pretty cold but when I put my foot down turbo boosts up in the high revs and then engine light comes on, when you put your foot down with engine light, the engine cuts out or gives you whip lash. When you turn ignition off and then back on light goes off only mods im running is Blitz air filter with standard intercooler, hi/low bypassed and boost gauge. Not sure if its boost creep, knock sensor, lamda sensor? Wondering if anyone has any ideas,?
