anyone ever lose power after hooking up a jacobs rotary pak?

I just hooked mine up and it just feels like there's no pull at all anymore. I'm pretty positive it's hooked up right. I had to adjust the idle up after hooking it up. When I step on it it just feels like it's falling flat with no power. The exhaust note sounds a bit different as well. Hmmm not sure what I could have done wrong. Car is N/A, S5 rotors, TII housings, street port, bigger secondary injectors, premix, stock plug configuration. Should I try different plugs?

mine works great, haven't had any problems with it so far. Could be the coils.

Yeah I bought it used a couple years back or more off a guy on teamfc3s but I've had to do some motor swapping since then and only had it hooked up once before briefly. Anyway to test the box?

Coils work fine when they're hooked up to the motor directly. The leading coil is spliced for the rotary pak and when hooked up it just doesn't feel right. Throttle response is very poor but it runs ok
