Burger Motorsports JB4?

Just wondering if anyone has tested this out or has any experience/reviews of the JB4?

If it doesn’t touch the trans…avoid it like the plague. It’s been around for years for the ST…there’s a reason nobody uses them on this platform. I use HP Tuners on my ST, my GTI has a JB4 on it.

Used a JB4 on a Honda, but as stated above, much better options for the ST. ZFG has been the best tune/tuner I've dealt with (Livernois, Ford Perf, Lund, PBD). Don't use a piggyback unless you have to.

For the ST, it'd be ZFG, Goosetuned, Ford Perf, and Livernois to name a few. Not a ranking order, just naming some "reliable" ones, but I'd use ZFG again in a heartbeat.

FYI,

I tried to document my experiences here:

thanks for the details! I'll dig into both the ZFG and HP tunes.
