I have messed with the timing alot on my mmm in my buggy and found it does just what it's supposed to. Ups top end rpm and reduces bottom end. Does create extra heat if your gearing is off to start with but I typically run 0-10 degrees on the small indoor tracks I race at and gear up if I want more speed. Works really well on larger open tracks though to really get movin.
