JB4 or Stage 1 for 93 octane

strig1 · 07-25-2014, 03:50 PM

Is the JB4 worth the extra money/hassle over the stage 1 if i don't plan on getting any other performance upgrades (maybe an air intake but ive heard those dont do much on the F30). I dont plan on ever going to a track just setting it in one mode and leaving it alone. Also any input on the intake would be nice

Just get Stage 1, to run map 2 on JB4 they suggest a downpipe upgrade as well.

in terms of power probably not.
But the Jb4 has more safety features and is more linear than stage 1.
