I do plan on getting a fuel pressure gauge with this setup.

There's your problem

Except that walbro's, whinboros', walsucks, wilpuke, all those pumps are HORRIBLE pieces of crap. I wouldn't trust one on an n/a car. Garbage

We can't be, mathematically a 2-3 lambda bouce would be 29-43:1

That's AFR's, not Lambda. Lambda = actual AFR/14.7
