yea, thats just sick.

but why the HUGE jump in performance from just .3 bar? i mean, it went up almost 115 hp from just that little bit. doesnt that seem odd?

its a big turbo +4.35psi. i thought it was a lot, but didnt seem outrageous. it actually went up 90.1whp from the 4.35psi increase, then later hit 499.9 (i assume there was a bit of tuning). so i imagine the lower number would increase as well.
so, roughly, 20.7hp/psi. doesnt seem too huge compared to the size of the blower pushin the boost.

at 1.2 bar the turbo is just really starting to get into the efficiency zone.
