everyone is saying there hitting fuel cut i am boostin 12 psi no fuel cut, i also have apex cat less dp greddy boost controler injen intake and underdrive pullys it pulls so hard its rediculus. tires roast by just floring it. just wondering why everyone elese is fuel cutting and im not???
 
it pretty much depends on how much air the maf is seeing. lots of people are hitting fuel cut now since it's getting colder and colder air is more dense which means more air per volume is going into the engine which means the maf will max out at lower levels of boost.
 
Higher elevation = less dense air = MAF sees less air molecules flying by (assuming all other factors are the same) = fuel cut will come in later
 
I hadn't hit the fuel cut at all (spiking at 9-10psi, holding around 8), until I drove my MSP on a 10 degree day in Albany, NY (almost dead on sea-level).
 
When I installed my EBC, i accidentally set it to 2 bar. Needless to say I hit fuel cut often. After driving like that for a couple of days, I figured out how to adjust...and also figured out I had spiked to 18.4psi...
 
haha thats ****** dangerous scott, musta been heaven tho (minus the fuel cut) doesnt 10psi seem so slow now!?
 
I have been hitting fuel cut like crazy the past couple of days. It sucks I think i'm going to turn the boost down for the winter. I don't want to put in the FCD becuase I figure it is cutting for a reason plus I don't have an A/F guage. All I know is fuel cut feels like hell on the drivetrain. I hit it for the first time yesterday and I'm learning to drive around it.
