boost question
I just bought an 04 superduty and I hooked up a boost and EGT gauge and the boost guage is only showing about 5-6psi of boost. I asked a couple of mybuddies about their trucks and they said it should be about 20-25psi. All the truck has is and Edge EZ towing module-60hp/100ftlb and a straight pipe. Any help is appreciated.

The guage is "t"eed into the vacuum line that goes from the intake manifold to the MAP sensor. Im also not sure what the truck should be capable of. I just bought the truck about two weeks ago and it's my first diesel. The only thing I have to compare it o is a not stock mustang.

I called the local ford dealer and spoke witha diesel tech today. He said that the truck only make about 5-7psi when your just cruising around. He said that on the interstate, if you floor it, it might spike to 20psi. I was just wondering when you guys are raching over 20psi and is it different with a load than just cruising around?

I can nail the pedal from a dead stop and produce 20psi very quickly. Pulling up a hill I can make 30psi (pulling 4,500lbs trailer). My truck is completely stock and my turbo is 1 week old courtesy of Ford. I drilled and tapped (off of the truck) the intake elbow for my boost gauge.

Tapping into the MAP line like you did will cause the readings to flutter a little in the higher ranges (above 15psi generally). As mentioned above, tapping the intake elbow will eliminate the flutter at all ranges.

because the turbo was just replaced 4,000 miles ago.
