Default forester xt with vf39 swap, need tune feed back.

I have a log and i couldn't find a place just to post datalogs. I just swapped to vf39, but swapped put inlet, hoses and a bunch of other stuff at the same time. New intake and tgv gaskets, and now it's all back together, it seems to have a leak or something going on. Doesn't make more than 9 psi, when target should be 20. If this needs moved, please do. I just needed to get it up. I'm going to grind over all my gaskets and connections tomorrow...any feedback is appreciated. Oh and i'm running cobb vf39 93 octane map. love you,

You did long log, you need to start log when you push it and finish when you lift you leg , all the travel from your home to wherever is not important.

Yeah seriously lol.. and change the timer too. You don't need that narrow of a window.

You need to do a boost leak test Wgdc is low. Do a full pull all the way to redline to.

Your fueling is horrible...the car is adding or subtracting up to 20% fuel and points when your driving. When your car is idling its pulling 15% fuel. That right there is already a problem.

What year Forester?

It's an 05. Ill do some shorter logs. I was waiting to get my exhaust to drive it more. It was super loud with dp dump
With the fuel being pulled at idle i was a little stumped. Its the ots stg 3 map from cobb, and im only seeing low boost also...maybe a boost leak but doesnt explain idle
