I'm using the SLS boost controller, quality boost controller. I believe it is installed right, I don't know if its creep I guess, because it just climbs right up to 20+ psi. stock wastegate, stock o2 housing, 14b with 16G compressor wheel and the exhaust is stock downpipe and stock cat, and thats it. I"m posting a pic of the controller tell me if its hooked up right, the bottom goes to the nipple on the elbow and the side part goes to the wastegate nipple.
