I drove it for the first time today to work. Still no wastegate but I took it up to 6psi anyway. There is a noticable seat of the pants difference over the spearco and this is only at 6 psi, I imagine the difference is going to be much greater at higher boost levels. At lunch I hooked a guage up to the brass elbow on the turbo and compared it to the boost guage and they were within half a # of each other. I have 3" tubing from the turbo to the intake and the intake opening is 3" also. The only thing that's not is the 62mm TB.
The best thing is the very improved cooling over the other FM. I didn't have time to hook the fans up so I was driving fanless. With the other IC the car would overheat quickly going down the freeway at 65mph if I turned the fans off. I still haven't put a thermostat in yet and today at a steady 35mph cruise the temp went down to 140 degrees on a 90 degree day with no fans. It cools like the IC is not even there.
