Right. A flat torque curve means that it keeps pulling. A torque curve that goes up means that as rpms build, it pulls at a higher rate. You'd see that with many turbo apps -- as the turbo spools up, the torque increases, but prior to the spool-up there's not much torque (aka turbo lag). Now, what concerns me about Pablo's curve is that, based on how the curve drops off at 5k, it means that as his rpms climb from 5-7.5k, his car is actually decreasing its rate of pull.
