thanx for all the info guys, i am still stumped...i have an STS .30 in my dominator and it is absolutely unbelievable. i ran .12 STS motors in my touring cars a few years back and they were awesome too, tons of power and very easy to tune. the sts .21's dont really awe me like the 12's used to so i think i am going to go wit either a WS7 or the P5X since they are very well proven and Werks seems to be a newer company
