Message Sorry about the awful quality, the frequency rate on my gauges make it almost impossible to read. But when I get to about 5 or 6psi the a/f numbers go way lean. The fuel pressure shows on the bottom of the boost gauge (almost impossible to see). I'm at maybe 48psi fuel at 6psi boost.

The second video shows a couple of pulls at higher rpms with no issues and plenty of fuel pressure (50-60psi at ~16psi boost).

Any more thoughts? I've heard the stock wiring is just barely under the amperage limit for the walbro 485, but that's when it is being pushed with really high flow. Mine seems to keep up fine at full pressure...

Third video of a cold start (a/f stays around 15 when FULLY warm):
