Just done my first rolling road in a MY01 WRX with ITG filter, Scoobysport back box running on Optimax. I was pleased at first with the top end power figure of 225bhp but once I got home and looked at my graph in more detail, my peak torque is only 190lbft. Is this as a result of the minor mods or is it likely that the car left the factory like this. Is there any thing I can do to get back the 25lbft that is missing?
Thanks
Steve

Could be an anomaly of your rolling road run (there are many factors to control and it is never perfect). Would suspect that before a problem with your car unless you boost pressure is low for some reason.
