    boost to power relationship!

    just wondering, what boost are people running, and what power/torque to go with it. i had a RR print out of 234bhp/278lbs, with wheel spin. running 20 psi overboost and holding 15psi. thought id get more, so how about you?

    Is the boost not more in relation to the torque?

    from what i gather its not just about boost pressures, also fuelling and ignition have to be tinkered with to have the car running efficiently and performing to its full potential....?
