How to downgrade Jb4 to Jb3?
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 Orange County area 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! |
