My EP3 feels pretty good in high rpms but in lowers not to much .... the car feels like no power from idle until reaches 1800 or 2000 rpms its like a " hole " in the acceleration that feels no power but after it respond very quickly and fast. this problem increases when i try to climb a slope sometimes i need to shift to 1 gear and then 2nd because if i intend to climb with 2 o 3 gear it loose the power very fast ...
I don't know what can cause this problem, the engine has cams stage 1 aem v2 intake and that's it

 

if rpms climb fast but car is not giving enough power like it should but, it could be your clutch giving u a hint.
