I have a dm-5 boost gauge from plx devices. There was a mix up on my order of a wideband kit and instead of a wideband guage, it came with a boost gauge. I'm giving the supplier a chance to make things right, but if he doesn't come through, I need to know I can get rid of it or trade it on here for a dm-5 wideband afr guage. I'll post a price if the exchange falls through. Tim
