Ive got a 2018 l83. Just installed btr stage 2 cam, gpi worked the heads, tsp long tube headers, whipple 2.9l, and soler lt5 ported tb. Had truck tuned by only tuner within 2 hours drive. He did admit not knowing anything about gen v but is very reputable with earlier generations. Truck was tuned off narrowbands. wondering if anyone could take time to look over tune and base tune to help with direction to go. Ive got an aem odII port wideband ordered as after researching has lead me to no knowing best way to tune gen v.
