Ok so I started to clean up the harness. Cut a few stray wires,tape up a few shaved wires. And all of a sudden I went from running Lean to Rich. Still breaking up,but it's very rich now. Will jump on the harness again today.

What wires? I am running super lean and can't find the issue. I'm sick of buying random parts to try and fix the issue

Speed density cars don't break up with boost leaks, they just don't make the right amount of boost. If it's not the map sensor it very well may be a fuel delivery issue. First thing I do to an sc is bypass the fuel ecu, even if the car is stock. Try that, then go from there. disconnect the map and see what it does.

and im running a stock fuel pump. Any other ideas will help
