Happy so far, everything trouble free. I need more HP. Looking to install BBK ceramic longtubes and the non-catted off road x pipe. Can I use my current tune or do I need a custom tune? If so, how and where do I get it?

Custom tune is what you'll need. Our dealer locator can help you with finding one. Most all the big online tuners use our stuff as well.
