that t60 is a retarded turbine/compressor matchup imo

basically your turbine has to spin way faster to move the same amount of air as a 10cm turbine.....which causes it to operate less efficiently.
I completely understand that (though I am surprised I hit and Hold 23.08psi to 7300). What I find surprising is:

My car will trap 120-121 on 93 pump.
Most of Juniors 35R pump cars trap 123-125

The last time I was on a mustang, the Stg 2 STi before me made 262whp. I made 304 on RG and trapped 114.

This 4.0RXT should be a 124-126 car on pump, in the stock location. Thats just nuts.
