Interesting that a couple of you describe the HX30W as laggy. Obviously you haven't drive an auto D1/D2 lately!!
Prior to my HX30W I was running a T25G - basically a T25 with a larger compressor. No intercooler.
Wastegate wired shut, decent low-mid performance but definitely choking under high load or RPM. EASILY saw 750decC pre-turbo.
With the HX30W and same fuelling I haven't noticed any increase in lag, and max EGT has never gone above 650degC pre-turbo no matter how much I push it.
Anyone with a laggy HX30W running a tacho? Roughly what RPM are you seeing significant boost and when do you hit 20psi?
