Car: 05' LGT Modifications: GS Up, CNT Down, GS EBCS, Infamous tune Problem Description: Maxed A/F Learning in column 3 of Learning View --> - Boost/Vac leak Recent Modifications/Maintenance: a couple months of driving stage 2 tune As indicated in LV (see attachment), it appears that I have a typical boost/vac leak. I've been chasing the leak down for a couple weeks but to no avail. I've been told that it appears to be pre-turbo. I've followed every hose from the turbo intake pipe, and all appear connected and solid. Additionally, I have a boost leak tester (just the crappy cap-off the turbo intake pipe w/ gauge and compressor fitting), but it hasn't been helpful to the spot the leak using soapy water. Does anybody have additional suggestions of where to look in view of the attached LV ? (in other words, does the attached LV indicate where the leak may be) Is it strange that the maxed value appears only in column 3 (airflow range 10 > 40)? Starting to think that the intake pipe might actually have a a crack somewhere..... Oh, I forgot, I'm a total newb, and most certainly appreciate any direction you can provide (besides yet another link somebody else's opinion on how to conduct a boost leak test). If somebody would help me chase this down, there would certainly be one or eight ice cold RC Colas involved....
