I would like to know this as well because I received my set of JBA Shorty Headers and was planning to have them installed soon.

do some data logging and check your ltft's during normal steady driving/cruising and re-adjust your injector slope as needed in order to get your average ltft's in the 0 to -2 range...

not sure about that, but you will need to get a custom tune created now since you went with LT's...
you'll get trouble codes thrown from the O2 sensors, so you'll need to get a custom tune created for ya in order to disable those trouble codes...

It may or may not, depending on their location and brand/type, but it can all be handled through a bit of Lews magic.
Good choice to go with the longtubes, they are a great addition.

I have shorties on my 06 A4 GTO and they made a big difference. High flow cats are over priced for the 1 HP gain over stock though. And as CANUCKPREDATOR said, the Diablo tune works well!

I've only selected the 91 Octane Tune. Does the Diablo Tune use 91 Octane also or something diffferent?
