ok here is my set up swap motor from a 04 5.3 from a Avalanche drive by wire 04 ls6 cam and springs 8.1 marine injectors (42lbsers) stock intake with a psc1 (4.25 pulley should be no more then 8lbs of boost)....I plan on deleting all emissions system .... I am using hp tuner pro....Plus this is my 1st time tuning any will be welcome

1. do i need the 02 sensors for tuning will they make it easier???
2. should i use a 2bar or 3bar do I even need a 2bar to tune at only 8lbs of boost
3. I was told that is hard tuning fi with drive by wire should I swap to drive by cable
