Chasing lean/misfire the last 6 Months. Built Longblock

[p00t]

I looked through those pictures (thanks for linking them). And I am going to say you are fine. The 5th link top pin would be touching the top of the tensioner if you were off a tooth. Everyone is going to see TDC differently depending on how your look at the pin on the front cover, and everyone is taking a shot from a different angle. Kind of need to average them all haha.

Further ideas:

Clamp off brake booster line, could be a big leak if the diaphragm is torn.
Clamp off PCV line in between the manifold and PCV (sanity check)
Max out TTP MAX settings in the tune, TTP MIN can only make you RICHER, check over as much as you can.
Any codes? If you watch the ECU flags while running does the start switch indicator go to off after starting?

Already blocked the booster line, my brakes do feel spongey and I just redid my lines/fluid so maybe it has a small leak but when I blocked it I had no change. I already blocked the recirculating pcv stock system and just have straight lines off the box and valve cover to a catch can.

The TTPmax is maxed out and TTP MIN when I leave it stock runs pretty rich but soon as I touch throttle it leans out completely on cruise.

Ecu have 0 codes, have to check the start indicator though.
