You'll notice an IMMEDIATE difference. After a few days, giving the ECU time to adjust, forgetaboutit. It's sickness, bro. It's so sick, I'm trading mine in for the new JB3.

Swap out your intake for BMS Dual Cones, put in a JB2 or 3, and live the good life. You don't need no stinkin numbers or drag times or dyno results. Just drive the car. You'll love it.

You'll feel the difference but i was kinda disappointed. I raced my friend's stock 335 with my jb2 from a 60mph roll up to 120 and only took him by a car.

Get JB3 and re-race

Rac3rX · 02-27-2009, 05:09 PM

yea JB3 is a bit step up from JB2 unless your running a h pill or 2 and a r switch, i was getting 4.6 0-60 with JB2H with JB3 1.22 on map 6 im getting 3.9-4.1 and 12.5 @ 110, tomorrow ill see what i can do on map 7 with some slicks

I liked the JB2 but I would agree that the JB3 is better.
You don't have to do the solinoid bypass and it's a much better overall tune.

FWIW, I have a JB2 just sitting in my house. 60 bucks? Sorry fot the

Can the dealers detect that the older JB2s have been used? I read that they had to remove the green and blue wire to avoid detection and new JB2s only have yellow and black. Is this correct?
