I have a good racing buddy that has one and he likes it, for the most part. It has an insane amount of pinch!!! He has a gallon through his already, and it still sticks ALOT at tdc! It also runs quite a bit hotter than most engines at this time. It runs good, just has to be set more rich than he would like to help keep the temps down, and that really cuts into runtime quite a bit.
I'll see where it's at after a few more gallons before I make my decision about it.
