JB4 friendly shops?
Are there any JB4 shops around the DC area that can fine tune it? I know Mach V does Cobb so I thought maybe there is a shop that can fine tune JB4's as well?

JB4 cant be "fine tuned", but you can adjust some of the things with the tune like afr, boost, ect. read up on information concerning that, and make sure you know exactly what you are doing.

Have you been to N54tech dot com? Lots of good info there on the JB4. Terry's customer service is awesome!
