whats everyones feeling with the J valve on a 99 GIAC K04 setup?
i have the J valve in now but would i be better off with the stock one? im looking smooth out the boost.
im tired of searching.

if your looking to smooth out the boost the stock one would work better...and if your going to go that route ill buy your n75 j valve from you or trade you my stock n75 plus some money for the J

i had a j with my k04/giac and it was really awful to drive. it spiked much higher [21ish] but i really like the stock valve WAY better. much smoother, especially on / off throttle.
