It uses outdated technology. The fueling capacity and ignition timing is not nearly as good as the JB4 from a safety standpoint. The JB4 has better control of fuel, ignition and boost. The JB4 also comes with conservative maps out of the gate compared to JB3. The Jb4 is able to monitor all 6 cylinders now too.
The JB3 just rides the knock sensors and fueling is typically very lean in the low-mid range.
I'd sooner to tell you to save up but I do know guys that are still using JB3 to this day since 2008.
