I was a test guy for the yugofast controller. I can slow my .890 car to 1.200. It's not a magic deal, you still need to know your car and have it dialed. It will let you tighten up your dial in and adjust for track power, temp, etc. The Yugo is more of a launch control. I can run no glue with my cars and still run a number.

As far as handling big motors, I've run into the .4's @ over 131 with mine.... I run big boy neo, cobalt, ceramics and never had a meltdown. The difference between my Yugo-Fast, Difalco and Omni is negligible.....

If you're the kind of guy that likes to brag about running a Parma controller with a blast because it's too hard to remember settings, this isn't the controller for you. It's a tool to help you be more consistent....
