[auto180sx]

hey just wondering if any of you all have had experience with either of these boost controllers. just a little backround information:

SR20DETwanna make around 500hp :ylsuper want a relible boost controller that can hold atleast 25psiwant a boost controller with some functionalatie, as why i picked out those two

also, any reconmendations on a blow off valve? ive been looking into them, and at the moment, im thinking about the Greddy Type R Blow Off Valve, as its for use with higher hp applictaions.

Thanks, if any of you all could im me on aim to help me out a little more, that would be great, nissan91hatch.

would the stand alon be able to cover the bost controll? i was under the impression that they only did the fule map and timing.
