I love how you don't even ask what fuel he was running in your internet diagnosis - seems like a logical first question before launching into a piggy tirade. Saying JB4 is junk is like saying HAS is junk because there exists 3-way MCS coilovers. The JB4 is really good at what it does given the limitations of a piggy back. It's proven safe and relatively inexpensive - it's impossible not to be safe because the ECU protections cannot be overridden.
OP - fuel makes a huge difference, and those issues you describe sound fuel related - either bad or too low octane for the map you selected. For refernce:
