i'm a bit surprised your gains are'nt greater with the hi-flow at 10psi, i,m running basically the same mods but with full ces system for a return of 189rwkw on a stock turbo tuned by matt spry at pits, i,m interested to see what happens with more boost and r&r sorted what type of power you can really produce (i'm ready for turbo upgrade just not sure what direction yet)
goodluck.
