you dont want a lot of boost. more boost equals more pressure in the engine/intake manifold, and more pressure equals more heat, so I would think that 7 lbs is pretty reasonable considering a stock m90 makes 6-8 lbs. my xp cam, ported heads, intercooled car only makes 9 lbs. I wouldn't bother messing with the boost bypass valve solenoid, it only cuts boost in low traction situations and when the car is in reverse. you dont need the BBV solenoid.
