JBX Review

PeeGoo · 04-10-2008, 07:48 AM

Set it at 100% and it rocks. Just WOW.

94 octane.

Regular JB2 - you get pushed into your seat. A nice feeling. JBX @ 100 is just more violent. The car actually seems to squat down in the rear due to the power. A few more lbs/ft of torque, I may be able to do a wheelie.

I have an xi and never really felt the car squat during regular JB2 runs - car just goes and pulls. Different feeling with the JBX.

I'm not sure JBX @ 100% is a good daily driver set up. The power is so significant that you feel like the car is always on the edge.

I think my perfect setup before was the JB2 with UR DP. No lag and lots of power. JBX @ 100% seems like too much power if you can believe it. Lag seems to be there. Once I get the HFC DP's back in, then I think I may be done for engine mods. Actually, maybe a BMS filter and then I'm done. For sure. Really.

One big issue I have to track is oil consumption. As in the other thread I posted, once I set it at 100%, I seem to have started to use oil...

is their a significant power increase using the bms with just a jbx? or is it to hear the turbos spool and help engine breath. Cause i know with dp's the bms makes a more dramatic increase.

congrats on the install. now go WOT!!! now!!

i think you got it the other way around.

BMS by itself will yield you some gains although your butt dyno might not be able to tell. But with lets say a JB2 or JB2X in this case+a bms filter, the difference is quite obvious.

haha yea i was pretty impatient too. I drove 100 miles to pick it up straight from Terry. Would it have been cheaper to order and ship it to my place, yes. But would i have got it right away? Nope. Instant gratification FTW!

Oh and im sure you'll all heard it before, but the sound really is addicting

dhan · 04-10-2008, 04:08 PM

Sound Is addicting. Combined with my jb2h I can def tell a power diff and change in pedal to power delivery feel.

Congrats on the new mods! Be safe out there....

Mattscott · 04-10-2008, 04:40 PM

Mine is in the mail.

I don't wanna wait.

if thats the case i might consider this as a next mod. So lets i have a jb2h, what kind of gains can I see? 1+psi? rwhp?

Obviously i cant be certain since i dont have dynos, but im gonna say you'll probably see a gain in the range of 7-10rwhp with the intake.

the more psi you push the bigger the gains when using the filter. JB2H is a perfect setup along with the filter...i'm about to order the jbx in about a week or so.

Can someone please englighten me? What's the JBX?

That'll be quite a change. Prepare for a different feeling though.

It's an add on to the JB. Another little box that has an adjustable dial to increase resistance values to increase boost. If you've heard of Terry's "hot pills", it's the equivalent of 2 of those. Then there's also that little toggle switch for the "R" tune.

thatg · 04-11-2008, 04:10 AM

whats the R i dont see that addon on their site. will jbx or jb2h, some kind of dp and intake give you 400w , or do the juiceboxes not make as much power as say a procede or xede

T i h o r · 04-11-2008, 09:34 AM

Wasn't the R for racegas? Or am I on crack?

You can read everything about the JBX on n54tech.com. Basicly it's an adjustable add-on to the JB2 which allows you to configure the power output of the tune. I personally think it's a good option. Terry is very serious with his products.

batlin · 04-11-2008, 11:22 AM

The R switch on it is just for Race gas. I have a JB2H and am contemplating it.. but i also just might get another H.. since i never use race fuel, i just like the ability to switch it off when i need to....
