The tutorial assumes you will exceed the PCM's airflow limit.

So on 10psi it made 600hp and 600ft/lbs. Not super impressive or anything, but I think above 10psi it will start to make more per psi, if the turbo still has some cfm in it. We didn't use the MAF cause the IAT sensor in it was dead, and the tubing went from 3" to the 4" MAF housing and back down to 3.5". So the readings wouldn't really be accurate cause of the turbulence. So I wired in the stock IAT sensor and we're using a speed density tune. So there is a dead spot if I mash the throttle. The is a little hesitation off idle that I think would be cured if I used a MAF. Here is the dyno chart. You can see the lean AF ratio right at the beginning.
Also when I start the car while its cold and put it in gear it dies. So I think the idle needs to be elevated or something.
