No, you can’t. The real F-14 Tomcat is limited to 7.5G and -3Gm and so is this one. The ACFS system limits G under certain aerodynamic conditions as per the real aircraft. At higher weights, the Tomcat was limited even further to 6.5G. All aircraft performance reduces with higher weights ( more fuel or ordnance ). The airframe could theoretically endure higher loadings, but would be examined once back on the ground for damage.
