ECMlink lean under any load

I just did some reading on higher volume fuel pumps cavitating from using a stock sized "sock". Is it possible that the pump is out flowing the stock sock? I bought a brand new one, but it has been on every pump I've tried since I first broke in the engine. If it's a very low micron filter, not designed for high flow it could probably restrict the pump at a given flow rate?

I may have to see what happens if I remove that thing.

I know that my power transistor only got extremely hot when it went bad. It would work ok until it got too warm, then i'd lose two cylinders. I'm with you in wondering whether the wiring going to the PTU has an issue. Possibly check the ground wire(s) in it in relation to a body ground the car is using to check for an issue that way? Just a thought.

Chances are OP is never coming back but this thread was really interesting to read as I am having similar problems. I'm not quite sure if a sock can cause such issues but I believe low amounts of fuel in the fuel tank especially a GSX tank can cause a high flow pump to such in too much fuel and the return wont return it quick enough as well as heating it up and frothing it. So you end up with a pump going dry at the sock and the returned fuel gets overly heated since it cannot dissipate the heat in the rest of the fuel.
99% of the time I drive my car with maybe 5 gallons in the tank or just before Empty so this may be why I keep having such issues. I wonder if OP was doing the same?
