i am going to put my V2 TMIC onto my car soon.

i also need to get a boost gauge and would like to install a MBC.

if i set the boost to 11 will i hit the fuel cut very often?

in other words is a FCD needed at 11PSI?

thats only 25 psi at sea level. but you're in ND so I have no idea what your relative pressure is. my td04 runs to 12 psi and I only hit a cut at about the redline.

Factory fuel cut hits at around 11.7psi (26.4abs) at roughly sea-level.

In other words, don't be surprised if you hit fuel cut every once in a while.

would it only be close to redline like arctic assassin said?

i rarely go close to redline.

the elevation in fargo, nd is 899 ft. so we are pretty close to sea level.

It would cut within 3 seconds of meeting or exceeding ~11psi.

If you hit 11psi at 2000 RPM, it'll cut within 3 seconds.

You'll hit it a lot more frequently then you'd expect. I did....had to back the boost off. I especially hit it more frequently in the higher gears where boost started to creep a little from where I had it set.

thanks. that is good to know.

looks like i will save up for a FCD and do some reading in the stickies about how to build my own. even if i dont plan on going above 11-12 PSI it sounds like a good idea.

11-12 is about the peak efficiency for the stock fuel system and turbo, right?

am i correct to assume that hitting fuel cut will not hurt the car too much, if at all?

sorry for the newbish turbo stuff. i have been here for a long time but i have only had the spinny thing in the exhaust stream for a little while now.

I recommend a TXS FCD. You can adjust the cut so you can still have some protection.

We all have hit the cut more than our fare share, no reported damage.
