SCT x4 Use and troubleshooting

Supernoob question...

Do I just flash on top of the current tune or do I have to go back to stock then load the new one?

So what custom PID setup would be better to use than the stock setting from the livewire i have been sending you torrie.

CORE WOT =
RPM
Fuel rear pressure
Waste gate duty cycle
Spark advance
Manifold absolute KPA and volts
Measured AFR 1-2
IAT 2
Knock retard
TIP PRS boost KPD and DSD
 
I was comparing your fuel rear pressure to mine, just to get a gauge of how mine was doing and we have completely different numbers; Same formula to achieve these numbers but completely different. Am I doing something wrong?




 
Are you running "corn" in the fuel too Josephm? I think FoMoCoSHO is and would be pulling lower #'s than you as they test the outer reaches!
