With modern cars, if you take a stock car dyno it, than install a new set of headers and redyno without driving the car at all, would the gains be exactly the same no matter when you dyno (if any)? or would there be more gains, say 300 miles after the mod?

Really depends on the car, ie; MAF or MAP sensor based, narrowband or wideband O2 sensors stock, torque management, etc.

 

Yeah, definitely dependent on the car. Some of the newer cars will usually make more right off the bat and less as the computer adjusts things back to where it wants them. Older cars won't really do that so much.
