no start/flooding of 5.3 lm7

trying to get my 5.3 turbo build finished up and having issues getting it started.
heres what i have done motor wise

new crank sensor
new cam sensor
ebay vats deleted stock 0411 computer
stage 2 sloppy cam
80lbs delphi injectors

motor seems to be flooding/blowing flames out of the exhaust just barely turning over
leaning towards the stock tuning being the issue with the larger injectors
any insight is appreciated

Your going to need a startup tune with those injectors. Fueling is going to be way off base.

Your injectors are 4 times bigger than stock. Maybe more.
Chevelle is exactly correct
