under same boost situation or whatever the fastest map

I am going JB4 after doing all my research. Good luck with your choice, really can't go wrong, just make sure you really think about how hard you really want to push your car.

jb4s faster.. lol

ive been running JB4 and so far so good. However i would advise none of the above, when you're sucked in tuning world there's no going back. Stay stock! safest you can be and cheaper.. lool..

Both are great and both come with 14-day money back guarantees so you can always try both and see which one you like better.

If you want more info on the JB4, shoot me a PM.
