I really just want the Fuel Pressure. Because just got a good deal on a Greddy EGT and Boost. I have a White faced Greddy 60mm EGT Peak Warning Gauge that isn't working that I would trade the gauge and electric box but not the pthe probe for the Fuel Pressure gauge. Not sure if the Electric box or the gauge is bad on it though. It shows pegged all the time when you power it on. Sorry if I am talking too much on a for sale item.
