BHP: 276.5bhp fly, 239.5 whp

Im kind of confused, it feels like im really down on power and torque, with standard spec saying I should be 298bhp and 256lbft of torque, does anyone that knows how to read this able to give me some advice? As car only has 30,000 on the clock i wouldnt have expected this much loss. Also all sorts of lights cut in when testing, my slip light and abs light came on.
Could i be losing compression?
