Will the ECU Need to be reflashed evertime you make an upgrade?
For Instance I am currently going with an
RMR Intake,RMR Downpipe and RMR Exhaust
Forged BLow-off and a GFB MBC.
I have a S-AFC II I was going to install but if the reflash
can handle my requirements and still get me in the 12 Sec
Range I am happy.

My other question is if I up the boost to 20-21 PSI
and get a larger Intercooler,Piping Kit and Fuel Pump
Pressure Reg. and Injectors

DO i need to reflash again?
ANd what is the turnaround and the charge?
