Can you explain the difference or advantage of a flash versus a piggyback and vica-versa? Doesn't one (Piggyback) trick the the OEM ECU program into allowing more boost while the other (Flash) is a complete remapping of the ECU and all of it's functions? I'm a novice at this but I bought the Dinan Stage 2 for warranty coverage.

I know you listed the advantages of removing the piggyback before taking the car in for service but I wanted to know if there were any advantages on engine wear.

And I really like the Dinan flash and hope to get all the other overpriced items that help with the Stage 2 flash; exhaust, air box, intercooler, etc... now all I have to do is hit the lottery.
