Might be a stupid question but... (JB3)

doubleA · 10-04-2009, 02:32 PM

Just how big a difference is there between JB+ @ 75% and JB3 1.4? 'My brother' just placed his order and isn't really convinced there is gonna be a HUGE difference between the two... Can anyone, especially those who've made the same switch, chime in? The power and dyno curves seem to be pretty much the same on comparable maps/%'s (minus the slight top end difference) so its hard to notice a difference without actually trying both. Does 'my brother' know what he's getting himself into?

It will ship with the newest 1.4 BTW... thanks for your responses!

There will be a huge difference, even with JB+ at 100%. Just make sure you have a BT scanner.

Even if the butt dyno doesnt feel the diff, your car will thank you for it. JB3 has far better control and your car will run healthier because of it

So, powerwise, there isn't really a huge difference?

There absolutely is a huge difference. It's night and day and easily the best bang for your performance buck.

As I stated, a huge difference. Do a search. THere are lots of posts about the power of the JB3 and comparing it to other tunes, not just the JB+.

Not sure what dynos you're looking at, but a dyno between JB+ and JB3 will show huge gain differences.

the diff is huge, but if you are running map 1 on a jb3 you may not notice it as much but map 5+, the diff is amazing

by far best mod for you buck

HUGE difference, especially if you've got supporting mods like downpipes.

doubleA · 10-05-2009, 05:06 PM

Is the application of power that different from the JB+ as well?
