Default F30 PWG Pure Stage 2 Overboost - 10-16-2020, 01:58 AM

Hi- I recently installed an older jb4 I purchased 2-3 years ago. I updated the firmware with the latest PWG f series download and input the latest settings from the N55 big turbo tuning thread.

Log attached. As you can see, it's overboosting a lot.

I read about the need for cutting the diodes here - F Chassis N55 PWG ISO Firmware and Details - N54Tech.com - International Turbo Racing Discussion

but it also mentions this - " *** NOTE as of 11/20/18 we've started working on a new PWG integrated firmware that should provide most of the benefits of ISO in an easier to setup package. So if you have not cut your diode already hold off for now. *** "

So do I need to cut the diodes on this older Jb4 for it to work correctly?

Car is FBO on 91 with meth injection. Still on stock tmap.

Thanks!
