I believe ANLU is a 5.7 bin that uses an L98 cam and cop car injectors. Need to work the VE1 and VE2 to get the BLMs dialed in. Your cam is going to idle in the 50 kpa range whereas a stock cam will idle at 30 so your stock tune is gonna feed the engine using the 50 kpa range making it rich. Can you emulate? I would emulate, open a history table most recent and take fuel out of the VE in the cells it idles in. From there datalog and clean up the rest of the VE.
