Is it possible that you don't know what the acronym "LBS" means?

"lbs" is shorthand for pounds.

Pounds is abbreviated lbs because the origin is in the Latin word libra, which could mean both balance scales (hence the symbol for the astrological sign Libra, which was named after a constellation that was thought to resemble scales) and also a pound weight, for which the full expression was libra pondo, the second word being the origin of our pound.

"psi" means "pounds per square inch." A unit of pressure.

So when someone says they run 10psi or 10lbs or ten pounds of boost, they are all the exact same expression.

However, this is all really not that relevant as the pulley on my blower will make ~14psi on a stock motor at sea level, and I'm only seeing about 8psi due to altitude and less restriction by having a full race exhaust w/ longtube headers.

So I'd say since you have exhaust and port work that the improved flow is lowering resistance. You're flowing just as much or more than the next guy but you don't see the resistance on your gauge.

I'd say your numbers seem right for the mustang dyno. You definitely need to step it up with the head unit. I may be selling my D1sc to upgrade to an F1.
