sts has a cheaper system then powerhouse but powerhouse generates better numbers, i was able to get the STS at around $4000 and you can get the Powerhouse one without the tuner at $4700 or $4800, i would honestly spend the extra money for the powerhouse... cuz guess what, thats what i did and i would be loving it if my engine didnt go out but when it was working it was a blast at only 8.3 psi.
