Don't forget that you will have a pressure drop with your intercooled setup. Usually about 1psi. I initially saw 4psi on my 16G6 setup with a 5psi wastegate spring before I installed my boost controller. Also, I see full boost in all gears (11-12psi). I'm easier on the pedal in the lower gears to keep traction and still pull hard.

5psi is excessive. Your ic piping is probably 2.5" and is 0.25-0.5" to big causing both lag and pressure drop. Your ic could also be to large, but the piping is a bigger cause of pressure drop. 2" from turbo to TB should be plenty big, if you want, 2" to the ic and 2.25 to TB should also work.

He's only losing 1 PSI, not 5.

Damn guys. Finally I felt the boost in my own mirage.

To be honest I was kind of scared to hit it about 4700 rpm, lol. Torque is so amazing. In 1st and 2nd gear, my steering wheel was going all over the place.

On Saturday I'll make a vid for you guys.

Don't worry I understand, there are times when a little wheel spin is fun.

Hey, put little more money into wrx and you can notice that in awd also.

Can't wait until I go to the track. 6.5 psi = 13s all day

Yeah 13s seem a bit unrealistic unless you run slicks or something like that.
