I came acorss this and found it very interesting thought I'd share.
NOT MY CAR!!!
T-trim 3.00, AFM power pipe, 5.4 crank pulley, Snow kit, 8 rib, BAS, stock heads/cams/intake, built bottom 10cc piston 9-1 compression. 80mm Pro-M. BBK long tubes, off-road H pipe, MAC catback, 60 injectors, twin 255 inline AN 8 to the rails AN 6 return, UPR fuel rails. It saw 17psi on the dyno, 20 psi on the street. 17 degrees timing. (red line)
Turbocharged innovations custom 4v kit (Magicbus), T70 Master power turbo, Tial 38mm gate 14 psi spring, 3 inch piping, custom intercooler, same engine as above (stock heads/cams/intake) MAC catback. PMAS HPX. The Maf readings were about 900 counts so it has 100-150 hp in it before it pegs. AIT temps never got above 112. (blue line)

So with 6psi less the turbo still made about the same exact power and has a much better power curve (100rw under some areas), and I also removed the methanol injection that I had on it with the vortech t-trim?
The MPT70 has much more left in it I had a $30 boost controller that wasn't working right. The first pull it pegged my boost gauge a 30 psi. The dyno graph had it making 560rw at 4000 rpm and it was going straight up. I'm still running chambered mufflers so that might be holding me back alittle.
Good to see a decent comparison
