Normal boost psi

Hello all,

Quick question abut boost psi on the powerstrokes. When I first start my truck my boost gauge on my edge cts reads 1 to 2 psi then drops to 0. I take off on the road and driving about 30 mph on my dirt road it says 7 psi then I hit the interstate and drive 75 mph and it will read 10 - 11 psi then it will slowly drop. The other day I was driving into the wind on I-25 here in northern Colorado and I noticed my boost was at 18 psi. Are these reading normal? I have a stock 05 f250 with only a coolant filter setup.

After reading all the boost threads on here I am thinking that I might have a leak or my turbo is sticking? What you guys thinking?

Thanks

There are a lot of factors involved when driving, but at startup and idle it should be 0.

Mine acts about like yours. 18 psi just because of wind sounds high, but depends on the wind I guess. I see max boost of 28 psi, this is on my dash gauge.

Mine is about the same using an edge tuner for boost readings. I will get up to 30psi when I really harp on it but I might have some sticky vanes cause I feels like it takes awhile to build that.

30 on a stock motor is testing your headgaskets. Should be 28 max.
