What I said before about a balancing act with the MFD map becomes a little more clear.

Yes, the Desired ICP map can be increased in those areas where you wish for a little more efficiency. Before you get too excited about asking for 1500 PSI where there was previously 700, there will be a point where it becomes a bear to drive; we don't want that. Also the benefits will start to diminish at some point.

On a side note, those ICP-fooling devices like the Workhorse module and Edge Juice actually DO work. They command an increase in ICP and mileage does go up. They wreak havoc on the HPOP, but they do give you a decent power increase with some mileage if driven decently.

Ok... I think I understand now.

What negative effect would there be with having too high of ICP, touchy pedal, increased engine noise, too much fuel too soon?

What problems did those modules cause on the HPOP's? (1211?)
