Everyone's correct you need to see what your spark table has in it.
Looking at you Dyno graph your W.O.T. AFR's are too lean. I'd recommend getting more fuel into it before you starting too much W.O.T. tuning.
Raising your fuel pressure is a quick way to do it but that adds fuel everywhere, assuming you can maintain enough W.O.T. fuel pressure you can effectively add or remove fuel by altering your VE table but you need to base your changes off data logging from test drives in your vehicle.
Logging with a Wideband O2 sensor will give you some good info about your AFR's, even if you can't initially get Wideband data into actual logs you can get a passenger to keep an eye on the gauge as you carefully drive at W.O.T. (that what a Dyno does but without the vehicle moving).
