I am running intank fuel pump, inline fuel pump, sfmu,42lb green top injectors. I am using the 2.72 disk and my idle pressure is around 20, sometimes the pressure goes up to around 23 and it may sometimes go to around 17. My inaccurate a/f gauge reads in the green when first turning on car, and when i go wot it goes all the way to the last green on the gauge. I thought for 42lb injectors, the 2.72 disk is good. The 02 sensor is fairly new, the spark plugs gapped to 0.035 are a new also. Any suggestion or help is appreciated. I have enough problems trying to find my boost leak. Thanks in advance
