Total newbie here. I have a bb ecu with the initial tune for my combo on it. I want to download the tune from the ecu. Do I bootstrap it like I would to flash it? The tune is pretty lean on 7 lbs in rhe 13.5 range and leans to around 14.4 at 10. Ive verified fuel pressure is good. My understanding is the first step to take is to adjust the pump eff table want to make sure that is correct. Got my lm1 a d aux box all straight last night so I can now log afr, fp, rpm, map.
