Just Installed my JB4!

I love this thing! Install was realively easy and only took an hour. I have 17" snow's on right now and I was breaking loose in 1st and 2nd (rwd). I can't wait until I can put on my regular wheels. I am super impressed it brings me back to my B5 S4 days when I put the GIAC tune in it for the first time.

Was anyone else surprised how they packaged it though?

make sure you play with your settings, there is quite alot to tinker with. Stealth mode(gauge hi-jack), warm up flash/blink, gauge sweep on start-up, radio off, and if you're stock can flap on

Also if you bought it used, make sure you choose your correct model in the settings as well, so the guages match up.

Installed mine today too and man is it a lot of fun. I've already done map 1 and 5, changed to boost on oil at 50% throttle, can flap.

Needless to say I had a fun day. Enjoy!

Ya once you get the JB4 on the car you need some decent rubber to hold her down

Hell, I have Michelin PSS and can still break loose in 1st and 2nd! JB4 FTW.
