if your going to stack, make sure you log.
It will probably cause misfires because you don't have the fuel to support the extra boost.
You can keep it in your glove box and put it on at the track, or if your going to pull a run, but I wouldn't leave it on full time on that engine.
The jb+ is proven to add .02 seconds to a quarter mile time and good for 2-4 mph in the trap on the n55.
It makes your car think its driving at high altitude, so will increase fuel/air = more hp safely.
