Well I have run into issues with tuning the fitech in since the last update. Found that most of my problems boiled down to the MAP sensor being wrong. With the fitech you eliminate the MAF which on the stock truck motors means you need to upgrade your MAP sensor to a 3 bar MAP sensor. I found that EFIsource has an LS1 3bar MAP sensor that fits in the truck intake. I should have that by Wednesday or Thursday and should be able to take care of my over fueling issue.
