Over the past couple of weeks my BLM's have gotten very low at cruise 90-110, no matter what chip I put in, the car still wants to have low BLM's, it also seems to be chugging at cruise speed,,,,o2's are high 830 or more, fuel is set at 42-43 static [unless the gauge has gone bad] Yes I have been having MAF problems but a known good maf was put in and it did not help the BLM's,,,,,,Any suggestions ????
