Currently beta testing the JB4 PWG ISO firmware with an MHD BEF. My car is currently FBO running a stock turbo and 93 octane. I can report additional smoothness with the BEF over the JB4 alone, it has also made the car feel a bit more consistent. Power gains are minimal but my butt dyno says I’ve gained a few ponies. The power on 93 feels similar to a small mixture of ethanol with a stand-alone JB4. Once the weather improves I’ll be experimenting with an e40 mix of ethanol. That’s where I expect to see the biggest gains in overall drive-ability and power.
