Yes, SG2. However it takes the ECU about 60-80 miles to sort things out when a change this big happens. After plugging it in the idle gph shot up to 0.20+ but has settled down to around 0.16 which is about where it was before.... Maybe the vacuum leak was enough that the ECU couldn't fully compensate and therefore it was running a bit lean??? but that doesn't make sence, I don't know....I guess I need to do some testing. My SG has the AFR and O2 voltage programed in as Xgauges, but they often display crazy numbers....
