obiltagi3 · 12-04-2012, 01:46 PM

So unfortunately i am unable to use the Stage 2 Jb4 and am forced to downgrade to Stage 1. How can i do this? I purchased it from my brother so its not like i can return it for the downgrade. Is there a way to downgrade it?

If not, is someone looking to upgrade their jb3 to jb4

Thank You

I guess i do not have the right connections for it in my car? I feel kind of iffy about my car not having the right wires.

JB3 is an old tune for an N54 powered car. You want to go from stage 2 to stage 1.
You are in so cal. If you reach out to terry you should be able to get a correct one quickly. Hell I remember when I lived in So Cal, I would just reach out to Terry and head up to the valley to get things taken care of immediately. Customer service at it finest!

The OP is confused. He is referring to the BMS N55 stage 1/Stage 2 tune.

JB3 is for the N54 and he has the N55.

Just to be fair, when I got my stage 1 in the spring it was still listed as JB3. So I have a tendency to refere to my stage 1 as a JB3 also because that is what it was called then.

From my order:

Product
Model Year/Build Date - 2010 - Jan 2011 (Harness A)

Product Code
JB3B1
