OP seems to have a nearly identical MPS build to mine -- looks just like my MPS 2.5 Powerfactor SS, in fact. The turbo output seems to be very close to my 10cm hta68 (figures below), as were the tuning conditions. My greater output seems to correlate with the extra boost I am running. Dom doesn't like my hta68 very much -- but he's done a damned good job tuning it. He really does like the Blouch turbos. At this point, especially with the 6-speed they just installed for me, my next move will likely be a 20G-XT.

My question for the OP might be why not go bigger than the 1.0?
