I just bought a 07 Si 2 door coupe, few questions, I know with the newer mustangs 05-07we tune at our shop they neeeeed to be flashed when putting a cold air or and thing else to the motor for that matter or it goes into a lean mode and engine light comes on. Does this happen with these cars? I own a few mustangs first honda so just need some info all help apreciated. First plan are the basics cold air,cat back,header. I have 1100km on it right now as soon as it hits 2000 or so im going to throw it on our dyno. thanks for the help

no, you don't have to do a reflash for simple I/H/E stuff.
