It's not a bad thing. You said you did internal work which probably raised your compression ratio that rasied ratio usually will cause a car to Ping (detonate) running lower octane (87,89,91) rated gas. Running 94 will allow you to take advantage of the mods that you did to your engine by tuning.
Higher Octane dosen't increase HP/TQ it just helps to keep Pistons from coming out the side of the block or through the oilpan by helping reduce Knocking and Pinging. Tuning is where you get your HP from.
