Struggling to run Tekkit

[Kack]

I've downloaded all of the Tekkit related packs and even gone on other websites, and every time I seem to lag when I use any ProjectE energy relays and energy condensers in a power flower formation. I decided to build basically the same thing that I did in my survival world in a creative world. It's literally just 5 power flowers generating gold ingots that pipe to 1 energy condenser making diamonds. I get no lag in any other minecraft mod, and I wasn't lagging before I put these power flowers. The lag seems to be only sudden dips where the game freezes for a few milliseconds, but it makes the game unplayable. I've tried lowering all of my graphic settings to the point where it's incredibly blurry. I'm not sure what to do and I really like that modpack. Any help is appreciated.
