my first tune was done by intense racing and damn was it f***ed up. wideband gauge went straight to lean bypassed all numbers and only had 4 lbs of vacuum. Random junkyard pcm had a better tune than his

Log Mass Airflow Frequence (Hz), Mass Airflow, Oxygen Sensor Voltage B1S1, Injector Pulsewidth B1 and B2, and the wideband. Let it idle up to temp then take it for a short drive.

this it the first time i have gotten over 1200 rpms. icy roads here so no drives for a little while and just got the rest of the wide band parts tonight. normally i crack the throttle and it dies instantly. 5 hours of trying to find a non existent vacuum leak

figured out part of my problem is i had a bad pcm
