If yes, how is it? Pros and cons?

dont personally have it, but shiv himself took me for a ride... all i can say is WoW, hella fast!!!

what all is added with the stage 1 kit?

Turbo-back exhaust and engine management (xede system) tuned.

Like Aaron said, it's fast. Typically 40-50 wheel horsepower with full stage I.

Pros:
*tons of power and torque
*better-than-stock driveability
*better fuel economy (this is theoretical- once you add that much power to any car, you can't keep your foot out of the throttle long enough to see how much better ;))
*No more detonation problems on 91
*Ability to take advantage of race gas with dual maps

Cons:
*No plug-and-play harness due to lack of availability of factory connectors at this time, meaning it needs to be spliced into existing wiring. Not as daunting as it sounds.


Also, since you are in Hawaii, hop on the local forum and figure out which folks near you have Xedes and ask for a ride along. ;)

Hey Ban Suvs, when do you think the factory connectors will become available, and when will the website be updated to reflect the Stage 1 kit being available? (I have a feeling the answer is the same for both)
