I got the 93 octane one.
I specified to James that I had the code 3 pulley, needswings cai, and iridum premium
plugs one step colder gapped at 38 (Needswing's recommendation)

my history is this...
1st I got the needswings cai - nice little power boost, not mindblowing, but VERY
cool supercharger whine - worth the $$$
2nd I got the newest code 3 aluminum pulley - totally mindblowing power down low
(and up high, but downshifts kinda optional now unless I want warp speed)
Pulls like an absolute monster - so worth the $$$ its not even funny
3rd Just got the chip back from InMotion last night. I always thought the car ran
kinda rough, even stock, throttle response slow and even bogged sometimes when
cold. All thats gone. This thing purrs like a kitten now - totally effortless power, and its running
like a swiss watch. Lots faster? Its faster, but running so smooth that it makes
it hard to tell how much. First impressions from one commute is yeah, its pulling
quite a bit harder, but Ive got to drive it a bit more - couldnt dog it with the ATL traffic.
Well worth the $$$ if it were just for the improvements in throttle response
and the way the tune makes the other mods play so well together.

Happy happy joy joy
