Finally some free time today. I think I figured out why bank 1 was richer/maf voltage lower.
It looks like this clamp wasn't tight enough since I could pull move it with some force. Tightened it to as much as I could without breaking it
Also some more pictures since I don't think I've posted these before
Steering rack shims/ spacers
Steering shaft clearance is about a finger width now. Shouldn't be an issue at all
Passenger side. Excuse the messy downpipe haha
Tidying things up and looks like I have a small pinhole in the wastegate line! Maybe that's why it goes up to 12 psi. I hope so atleast
Also, thanks for the idea whoever posted it here. I tested the wastegates and they open at the same time but the guage isn't very accurate I think since it takes 20 psi to open it all the way. It starts opening around 4-5 psi but the guage is off since it's a cheap $10 pump
Edit: just did a pull after making sure there's no boost leaks and it's still at 12 psi and even 13 :/
Good news is my new injectors are working perfectly WOT (60% duty cycle now)but a little weird while idle which is understandable.
Notice the boost at 3000rpm
