Hello,

SO a friend of mine uses an Accessport and hes trying to get his GEN1 tuned HOWEVER He's having issues with the trying to get is LTFT but because his AFR is not getting target, its not ideal.He's so far replaced his o2 sensors and we SUSPECT that the MAF sensor is ok although the idle voltages are reading between 1.2v-1.3 (we will trial another MAF sensor to confirm).Hes installed the HPFP and has the CObb stage 2 mods and a FMIC (3" Intake and DP)Has anyone had issues with the relief valve not opening properly once the HPFP upgrade has been installed?

Please help

I didn't find the right solution from the internet.
