Another thing I would suggest would be to sell the JB4 and go to a Cobb accessport or an MHD flash. Both offer better control of your stock ECU whereas JB4 is a piggy back that essential lies to the computer. |
Slow down there.... OP has an N55. They do not need cleaned (walnut blasted) with anywhere near the frequency of N54 engines.
Also, from his signature, he has a 2012 N55 which means cobb does not support his ECU (unless support had changed very recently.)
