10 psi cruising at 75 mph

[cafryer]

Does this seem normal? It seems a bit high to me and im only getting 12-14 mpg. Any suggestions.

Sounds like the pw might need to be a little more limited with the maf but im no expert....

I hold + - 5 psi @ 75 mph

Got a brake dragging?

Got a brake dragging?

Never thought about that but i havent smelled anything.

 

[jmaz268]

just feel the rims after a nice drive...or check to see if your hydroboost is leaking too

Seems normal to me

i pushed between 8-10 at that speed but im higher, have more wind resistance and running bigger tires

 

[Dozerboy]

Head wind?

 

[wsmithduramax]

I run about 10psi also at about 75

 

[Harbin_22]

10# is what I see too. But I get 16-17 @75 mph.

I see about 5 psi at 75mph... so 10 seems high to me... but you are running a lift and 305's from what I see in your sig.... that may be part of that.

I'm closer to 5 psi also. That's on flat ground and no wind.

4-6 psi at 75 here

 

[Dirtymaxx03]

3 psi on flat ground at 75

 

[JMDuramaxLB7]

Mines at about 5-7 at 75. Seems a little high to me. This is with a stock turbo...
