gt35r sti on wastegate boost

I made a little video this morning while going to get coffee. The car is still running only wastegate boost (1 bar spring), and a very conservative tune. Don't mind my knocklite in the last clip, it isn't calibrated yet. Once I have some more miles on the motor I'm going to push 22-23psi on pump gas (not to mention 30ish on race gas), so there is still a ton of power left on the table.

Putfile - 2005 STI with gt35r and built motor 14psi break in

Not Bad. The EWG is set @ 14psi? Response seems to be fair. She's still in need of a tune?

The tune still needs work, but is not bad. There's a lot left on the table. It's a 1bar spring in the wastegate. I turned up the boost to 16psi last night... the 850cc injectors are already hitting 75% duty cycle! And it is moving 300g/sec of air. I am really tempted to put the factory maf back on the car just so I can have some datalogs showing a maxed out maf and only 16psi.

Looks like new injectors or AFPR is in your future.
