ah ok, well hopefully it will be on full boost before 4000rpm, i noticed micks gtx3071 took until 3800rpm ( correct me if wrong) which i thought was a bit late, cause mafia's came on full at 3200 which is big difference,housings may have been different.
The claimed 10% increase in flow doesnt seem to be true in that case, atleast on those boost settings and rev ranges, maybe with an external gate and E85 the hotside isnt as bad, and the compressor is able to get closer to its max efficiency then.
oh well ill see what happens with mine and then re-assess any improvements.
cheers.
