DME upgrade and Chargepipe question
I have a JB4 stage 2 for the n55. Someone told me to upgrade my DME if I am getting some issues with sudden jerks etc.
What is a DME? How and where can I upgrade? I can't find anything -_-. Just want a quick direct answer please also what does a BOV do on a chargepipe? thank you. |

When did you buy your car? Build date?

I don't believe you can and want to. Disconnect the jb4 and go get it done.

Sudden jerks?? Are you sure the JB4 was installed correctly? Maybe you're getting misfires??
Several possibilities without more specific details A BOV is an alternative to a DV, if you decide to switch from the OEM DVs to a BOV-setup, you'll need a new CP that has the proper connection |
