When using the mod, I test the timing of redstone repeater/comparator and torch and it happen that the timing of the redstone is slightly less than 1 tick. When just one repeater is used it makes no difference but in the case of multiple repeater it become visible.

Thanks for the report! Could you provide a screenshot of a circuit to demonstrate this? This shouldn't be possible, since the mod is just hooking into Minecraft tick events. Also, please provide the version you are using.
