ryephix#2

going to gaic tomorrow for their flash. i'm running-19%-alta intake-miltek
header&cat-back-380 injectors.THE BIG QUISTION: i have the ryephix#2 on
my work-bench. should toss that in also? remember stronger spring on
the by-pass butter fly. how will that effect things? on my 04 s i don"t
detect yo-yo but others that have driven my mini said they felt a little
yo-yo or surge. keep in mine that my sences are shot-(like my spelling)
i"m old,droped on head way to many times as a child & have had way to much fun as a young-man growing up. (read dead brain cell"s )

I'd say absolutely. I never had the yo-yo, but did the Ryephix #2 for the simple reason that it brings boost on earlier than the OEM spring. Because of this you will see a ~10% or so reduction in your gas mileage. But I've got to tell you, I like have discernable boost down low.
