I wasn’t sure where to post this so i picked here… 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, Oil Temp) 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](http://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. ---

Injectors are probably maxxed out if i were to take a stab at it. ---

Your form of tuning blows. You need to find a better setup like a powerfc/whatever they make for your car thats not just a hack. I believe with the neo you can only tune WOT and idle. On a turbo car from the factory you might squeeze by but not on an aftermarket turbod car. ---

maf voltage is probably maxed. put the stock sensor in a larger maf housing, ORRRR ger a bigger maf… a mustang cobra maf seems to work well for most applications. you just need to scale it properly and you will be all set. ---

It’s going rich or lean not sure? OK… No one is able to help you with that sort of information. Please provide relevant information: timing, AFR, boost, etc… Maybe a datalog? ---
