You just have to watch your AFR, I have an FCD stock tune and turbo with a hks intake and turboback 2.5" catless exhaust and a walbro 255. I get some pretty bad boost creep and with the FCD it just lets the car keep adding fuel untill it leans out so be careful.

Why get a little Resistor "Trick" Plug it in and Blow your engine box?..it;s like the electronic snake oil of devices.
Spend the 50 bucks that it would cost you to buy an FCD and put it towards a Rtek 1.5..or 1.7 or 1.8..or Tadah!..a 2.1!!
Here check them out. http://www.pocketlogger.com/
The 2.1 can be programmed through a Palm pilot.
it is the Cheap *** FC owners version of a Haltech!(no flames please on that comment!).BUT the damn thing WORKS great!..I bought TWO so far.
OH,,and did I mention that an FCD is built into the RTEK?

Hmmm. there is a problem here then. My car already boosts above stock. Its blown already too. I think it poosts that way because I have magnaflow cat back and some sort of down pipe. I dont know the brand. Ive been to the rtek site and ive gotta say that thing doesnt sounds anymore convincing that a paper clip. Sorry. I think I prefer to spend the money on something better once i rebuild. Im just asking this question as homework for future reference.

Would there be a benefit to upfeading my fuel system with what i just said in my last post? With the exhaust set up my car came with. Would it prevent my engine from blowing up?

You should consider running a better fuel pump and larger secondaries if you're boost is increased over stock limits.
As for any doubts you have about Rtek, their stuff is good. Thousands of us use it. And if I'm not mistaken (correct me if I'm wrong), Digital Tuning (the company the Rtek belongs to) helped design the ECU in many vehicles (including the rx7). They know how to chip an ECU.

Why wouldn't you pass smog? My car passes with flying colors every 2 years. As long as you have proper control over the injectors and don't use a walbro pump (use an FD pump), mixture under testing conditions won't really change. Walbros jack fuel pressure up, which means rich conditions at idle and under low-load.

Dude, get the Rtek. You can tune alot on it. It works with all stock parts. It has an FCD built in. You can add more fuel to your system to make up for to much boost. When you want to change injectors. Its just a few clicks on the screen. Since you have the nightmare of Kali smog laws. It looks stock so even if some one wanted to look under your carpet it would pass a visual.
This + a inexpensive wideband an you are off to a good start.

It air/fuel meter that reads more than good, bad, and fuked.
I really like the idea, features and price of the RTek. But a few things concern me- it's written for palmOS, a dying OS. (iPad over wifi would be nice) I'm pretty sure it's limited to 1bar of boost too?

I don't think that a none palm pilot option is going to happen. There has been a lot of comments about it in the Rtek section and I think that palm is it.
That is my only real complaint about the rtek. But for a "slightly more then stock" car it works fantastic!
My car.
87 T2
720x4 injcetors
walbro fuel pump
racing beat turbo back.
BNR stage 2 with stock boost (6psi)
With the wideband i can monitor my AFRs right through the palm.
Beleive it or not for monitoring, the smaller size is really kind of nice

I had sort of the same problem, but then with out any damage.
Previous owner put a 3" corksport exhaust system under the car (S5 turbo). But he also did an engine rebuild AND he ported the waste gate <!
Porting your waste gate helps a lot. I used to drive with the bung in fist, but later on i removed and i've had a fuel cut only once. Fuel cut hapens at 0.7bar, about 10psi.
Porting your waste gate would be the cheapes solution, however, it does not mean you wil not get a fuel cut anymore.
At the moment i am changing a little more things on my car. I wanted to upgrade the fuel system because of this problem, and one of the benefits of doing this, is that when you put a bit more mony and effort in it, you also prepare the car for the future if you had any plans AND after a remap you will get more HP.
The setup that i'm building right now.
I started with:
-streetported engine
-stockturbo ported waste gate
-3" corksport exhaust
-apexi air filter
-greddy type-RS
And a few other other things.
Upgrades going on right now:
-2x 800cc sard injectores at secundary
-S4 turbo secundary fuel rail
-aeromotive FPR
-walbro 255lph fuel pump
-rewired fuel pump, removed risitor relay
-run new hoses, my fuel rails will be connected parallel
-aftermarket wastegate actuator
-'93 - '95 apexi power FC in combination with the banzai racing adapter kit (you cannot run larger injectors on a stock map. Either tune the stock ecu or get a stand alone)
If you are going to use a '93 -'95 PFC, you will also need:
-second trailing igniter. A how to comes with that adapter kit
-map sensor and IAT sensor comes with the kit
-you need to make a custom intake from filter to turbo
Ehm, it actualy started with this, later on i decided to map it on 1 bar, about 14/15psi so these parts are also going on:
-hks twin power rotary ignition amp
-magnecor plug wires
-apexi AVCR boost controller
I hope this will give you some idea's to do.

I thought so but i'm not sure. I just got the apexi so im also prepared for what is still to come.
I beleive furb also used a afc neo but i'm not sure if that was in combination with his reprogrammed stock ecu.
@ bamato,
8 psi is about 0.55 bar. With the setup i had, open exhaust and ported waste gate. I got easely at .5 or .6 bar of presure. When i did had a fuel cut, i looked back at the gauges (i love the defi gauges with peak function) and its told me about .7 bar. And 10 psi is .69 bar.
