Cold air, elevation, clogged cat, faulty reading gauge/sensor, exhaust components all change PSI rating. Higher PSI is not always good as PSI is measurement of a RESTRICTION.

Example: my 80mm TVS pulley only makes 16psi thanks to ported head, header, and catless 3" exhaust. With stock exhaust mani and downpipe with 2.5" catback it made 21psi but was slower

X2! More boost doesnt always mean more power. I've got a 2.8" pulley and hit 15psi. I take it as a good thing

With a good set up someone with a 3.0" pulley could beat a 2.8... It's all in the tune and supporting mods

If you have stock exhaust you will see 16-17psi on a 2.9 at low elevation. I saw about 16.5 on stock exhaust and 2.9, now I see 15 on a 2.7

yes, yes it does. with the raw intake it screams, sexy sound. but i want to drop pulleys again. gonna maybe man up and try the 2.5 but im afraid of my stock pistons. but i am running about 25 percent more efficient than stock balts... maybe more when i get my 3in dp
