I also plan on re flashing the Velos tune...I'm guessing I need to uninstall the JB4 first though...such a headache.

For the charge pipes, I had mine smoke tested today, and first the mechanic used parts cleaner and sprayed it around to check for idle fluctuations which would indicate a leak. Then he put the smoke tester on the intake and tested for smoke leaking out...
