Ive got a boost controller with low n high boost ...... i run stock boost on the low so about 6psi on low when i wanna conserve fuel and on high i run about 12psi.
If you want 0 boost ..... then you shoulve bought a N/A.
Basically just keep the boost low, invest in driver training and take it easy. When your a new driver with a turbo car the wet weather can be very intimidating - its good to see somebody that wants to keep himself and his car in one piece
