300x revs harder on eco than on full power mode thoughts ???

[red300x]

Hi there members
Any one have an idea why my 300x would rev higher 7250 rpm on eco mode over full power mode, struggles to get to 7000 rpm also only gets 10-11 psi of boost.

You got alot going on. Your ski should rev alot higher than 7250. Should be right at 8000.
What ski? Any mods?
