I'd thought of that too. Mine are about 300 psi low, with one that wont hold 400 psi. Still getting 18 mpg. From what i read on the F1 website, they should be able to figure out how to flow as much or more than PODs, and reduce smoke. I like that idea. Might get back up over 20 mpg again.
I'm in for a group purchase if someone can get it set up. I'll be working 75-90 hrs the next few weeks (harvest). I might see about it after a few more paychecks.
