Sweet thank you. While I was on the site I noticed you guys don't offer the cracks and pops, is that correct?
You are very welcome. I do not believe that is something offered with the JB4 tune. That’s usually accomplished by dumping fuel onto the exhaust, which is counterproductive for performance.
