Installing DCi and JB2 ?

I just received my bms DCI and JB2. I want to install both of them this evening Which one would be better to install first. I was thinking the JB2 in case the air filters get in the way. Any thoughts or comments that can help save me time would be great.

Well to install the JB2, you need to take the engine cowl off. That will allow you to do both JB2 and DCI.

i would do the dci first then the JB2

Is it really that old? I'm surprised by that response a little bit. What should I expect for power when I combine the JB2 with the DCI

I got the JB2 from GMP performance online. Burger motorsports still sells them online too. And I'm not liking for huge power. Just a little extra kick to my daily driver and I dont wanna deal with check engine light and headaches. I will see how this goes and if all goes well maybe I will upgrade

If you can put up with the newbie initiation / hazing, you're all good.

Did you get them on? How do you like it?

You've started 3-4 pointless threads in the last few days

"Jb4 gas gauges going wild"

"Bms dci"

"Jb2"

You're not using the search function, just throwing shitty threads up when you have a question. If you really don't want to search, use the general questions thread

TO be honest OP, if you are going to go through the trouble of poking around in the ECU, you might as well upgrade to a full tune like the JB4. I remember giving my JB2 away around 2 years ago, because there was noone who would buy the outdated JB2 and that was 2 years ago!

Well i finished the install today and everything went great. Even with just the JB2, which apparently everyone shits on, the DCI sounds amazaing. That extra boost really makes a difference in the sound and performance of the intake. I have been driving pretty conservative to make sure the ecu fully adjusts to the new settings but I can already feel a big difference in power. For now these mods will do just fine for me.

If you're happy with it, that's all that matters!

Any extra bump in power feels great, then the mod bug will hit.

Enjoy it.
