i have been doing research for about 2 1/2 years now on my
tiburon and i have asked many questions but kept getting
led in the wrong direction. this is my set-up:

2001 Hyundai Tiburon 2.0 Beta
T3/T4 Turbo XS ..63 (hot) .50 (cold)
8.5 MM Magstar Spark Plug Wires
Spearo Intercooler (not too sure on the dimensions)
2.5 Piping (down pipe, hard pipes, exhaust)
Apexi SAFC-NEO Air/Fuel Controller
Bosch Spark Plugs (gap .34)
Turbonectics Raptor BOV
Turbonectics Deltagate ll 35 MM Waste Gate
440 CC Precision Injectors
Cast Iron Manifold
Meagan Racing Front Upper Sway Bar
Oil Sandwich Plate
255 Walbro Fuel Pump
APC Air Filter
OBX Upper/Lower Radiator Hose
Tri-pod Gauge Cluster (Boost, Oil Pressure, A/F Ratio)
Short Shifter
OBX Water Pump Under drive Pulley (to be installed)
OBX Alternator Under drive Pulley (to be installed)
Autoteq Fuel Pressure Regulator (to be installed)
Greddy Turbo Timer Profec Spec B II (to be installed)
ARP Head Studs (to be installed)

Sorry for the long list, but i didnt want to miss anything.
this is my problem... Okay now I have tried to get the Tib
tuned twice already, both times ending with the same result.
Basically this is what happens… when my car is about to
get into boost my car leans out(or is very rich, i cant remember).
All the pieces of my car are installed correctly. So if anyone
knows something that I don’t know please tell me know so I can
correct this discrepancy. Now the only thing I have that I
haven’t tried was a larger MAF sensor that i bought from
Sharkracing.com. Hopefully my car is freaking out because
the ECU can not compensate for all the air it needs to take in,
which hopefully the MAF sensor should take care of. The injectors
are big enough, so I know fuel is not the problem. sorry again for
the novel... thanks to all in advance.

what kind of tuning system are you running?

Sup bro... it's Arnel..... Honestly, I think it's the AFC. You need a better fuel management. I'm just not familiar on what is available as far as applications for your car. Look into a stand alone system.

who is doing the tuning? do you at least have a base tune loaded?

BadNews5

im pretty sure that emanage will work for this car
possibly aem ems????
not really sure what else

iceguyb14

probably some piggyback systems..

can you try and remember if its running rich or lean??

could it be you have a boost leak somewhere? if you do the ecu could think that air is going into engine but its really being leaked out.. causing it to run rich..

The stock ECU is probably freaking out, and no piggyback is going to be able to help that.

I was looking around at Greddy and HKS. Seems like the you can get the HKS F-CON V Pro for your car. Might have to call them cause I wasn't able to find a price. All of the other ECU's were piggybacks from Greddy.

Ditch the AFC and get yourself this: http://kfxperformance.ca/index.php?o...231&parent=261

Get tuned, have fun.

I'm with this guy. If your going to invest in all the shit to run some serious power, you need some serious engine management. Apex-i does not qualify.
