i had the jb4 on the first grey sedan - I have the Cobb Access Port on the 09 black one - I prefer the 'built-into ECU' vs the piggy-back - though JB4 will give you slightly better pull. Tell you what - if you're using run-flats - next time try the Bridgestone s04's - they hook the road like nothing else - and are $980 per set versus those rip-off Mich. Super-sports which are $1150/set.
Tires are critical - You'll see tremendous gains if you simply buy some regular tires versus those crappy run-flats.
