[QUOTE="Denver_SVT, post: 16305651, member: 72321"] Here you go an update: i tried setting displacement and MAF transfer back to what it was setting before the rebuild. Then i gave the maf 8% more and see how it does. Unfortunately no changes at all. The AF will read rich for 3 mins and jump to lean 17-20 and the STFT1 between 0.97-1.04 and LTFT1 0.83. After that i shut off the Adaptive and cats for temp to start adjust the maf based on STFT1 peak and vally to get the average. Still same issue no changes at all. It will read the first 2 mins 13-15 AF and then jump to 18-20. So, i think there is possibility for leak. What do you thinks, any suggestions? Sent from my HUAWEI matte 20 pro [/QUOTE]
