hello everyone.
i have '06 FX35 AWD, i have done some modifications; +2, MotorDyne 1/2" IsoThermal Spacer, and LMS Intake System

the first mod i did was the spacer and it was amazin, my car became faster specially when i race rolling from 40km/h or 0 .. i think i gained HP and no low end torque loss

weeks later i installed the LMS intake system and i did the +2 .. the sound was awsome, but i noticed later that my car is running slower i think i lost some low end torque


so what do you suggest for me? what is the problem? do i need to reflash? is that because A/F ratio (more air than fuel)?

 

Just keep on adding mods! Add as much bolt-on mods as possible then go and get a ecu-flash You got decent mods so far, go get exhaust system and headers, perhaps high flow cats too, you'll feel a definite gain.
