I just completed my 5.3l swap. I bought hp tuner and removed vat and changed my injector size and deleted most of the emissions stuff and some other random things... I can post my changes if it will help any... My situation is I don't know anything about tuning and what to do to get my truck to run correct.... I am taking it to a real to tuner but I need to have as much in place as possible to get it tuned...
Do I need to install o2 sensor to get it tuned
What's need for a sd tune (right not I have the stock maf hooked up)
Should I get wide band if so what works best with hp tuner
The truck is procharged with ls6 cam and 8.1 marine injectors complete stock rebuild


Any help would work
