Don't panic Mel,it could be the difference between dynos.I am concerned about the lack of difference in power after the install of the decent FMI/cooler.My soarer gained heaps of power when i did it.But my time didn't drop,due to excessive wheelspin.I put on sticky tyres and blasted 4.8secs and 12.9 for the 1/4 mile on a G-Tech(previous best 5.2,13.2secs with same sticky tyres).also,terminal spped at the end of the quarter is a very good indicator of power,and my terminal speed increased by 5km/h,showing a good gain.
With regard to air/fuel ratios,I'm not sure i can shed light on what the hang has happened,however i will offer this long shot of a suggestion.Your O2 sensor is faulty,possibly caused by being coated by lead,or the residues often left by octane boosters.The engine reverts to its emergency 'safe' base map for fuel and timing.Power is naturally less.Apparently these can be cleansed by stuffing them into a lemon for a while.Or an electrician can determine if the O2 sensor is sending signals or not.Yeah yeah,I know this is from left field,it might not apply.
