I've asked about this before but would like to again based on a discussion I recently had.

I'm using an electronic boost controller, internal WG on a stock SR with the 2871, I reach 15 psi at 4200 RPM. A friend of mine says he hits 20 psi at 3700 psi ( stock SR with poncams) and it's because he did the CodyAce external WG mod.

Is this possible? I know an external WG allows for better boost control below 15psi and above 20, but can it really help improve spool that much?
