WHO'S INSTALLED THE WAVETRAC AND WHAT DO YOU THINK SO FAR?

I'll start it off. Before the car would squirm rolling on the throttle in 2nd. but now the back end is shooting to the left and this has me perplexed. I seem to remember my brothers 396 Nova doing the same thing ... The weather is not ideal, it's cold and damp. Maybe I just have more power with this cold front? Maybe pulling the differential threw the alignment way, way off? Tomorrow I'll be looking for an empty parking lot to see if I'm putting down 2 stripes or not. Maybe the shop broke the thing and didn't say a word? 6th alignment of the year on Saturday. Somebody calm my nerves ..... Who has it installed and what's you car doing?
