I posted this earlier, on a similar thread:

Well, you're also hoping for a blown head gasket, rod knock, and maybe even a hole in your piston. How many times do you have to read that a FCD is a time bomb waiting to go off, before you get it? Fuel cut keeps you from doing something dumb, and blowing up your engine. Go ahead, use the damn thing, and while you're at it, remove the brakes too. They just add needless weight, right?

NO FCD!

A bad tune, is a bad tune.
Blaming an FCD because you failed to tune your car propperly in the first place is lame.
Pleanty of 7Ms blow without ever having an FCD near them,
just because the build/tune was off.

Bottom line,
If your going to play 'Tuner' with a turbo car,
you had better learn how to actually do it.

This includes having the correct gauges to play the game.
Not going by what someone says to run for fuel pressure,
or what someone else says to set your S-AFC to.

At the least, a good A/F ratio gauge, like a GReddy or Tomei.
Stay away from the el-cheapo 'rich-lean' gauges.
They are menat for carburetted V8s, and don't read into the super rich areas that a turbo car requires.
And exhaust temp, and injector duty cycle meters doesn't hurt anything either.

Work your way up to full throttle runs in stages, and watch the meters.
If you see lean-out areas, back off the throttle, and tune them out.

If you reach the high end of the the adjustment range with the S-AFC,
increase the fuel pressure, and start over.

A good tune is a good tune, There are plenty of cars pushing big boost, and high power without the use of a needless and dangerous piece of hardware. The danger, especially for inexperienced modders, is that a FCD will give them a false sense of security, and push them into doing something dangerous. As a good tune is achievable without using one, it is safer for all, to discourage their use.
