(Re) Installing a COBB accessport tune on the 997.2 GT3 and going for a quick drive

16:33 onramp pull
Time to re-install the COBB accessport tune on the GT3. It's kind of a long process with plenty of precautions so I monologue a little on various topics.
California smog checks now verify ECU checksums so returning to stock is required to pass an OBD2 scan. Some thoughts on the matter.
Quick drive at the end with one pull which spun the wheels into traction control. Whee.

Very helpful! Is the jump in hp/tq that noticeable compared to stock?

yeah there's a big difference in the mid-range from 3-6k rpm.
