Flooding problem, won't idle.

So i've been trying to get my car to start and idle for 2 nights now, and my plugs keep getting soaked in fuel.
Setup:
302 SBF
450cc DSM injectors
MSII V3.0 from DIYAutoTune
MSD Distributor w/ magnetic pickup
I Have spark, and the distributor rotor is lined up with cap terminal for cylinder 1 with cyl 1 at TDC compression. I even got the engine to idle for about 10 seconds, but this was with my fuel pump turned off and only running on the fuel that was left over in the cylinders.
I ohmed out my injectors and found 2.1 ohms so i set up the following:
PWM Time threshold= 1.0ms
PWM current Limit %= 30%
2 squirts, alternating
upper req fuel = 9.4
-40F cranking pulse = 8.2
170F cranking pulse = 2.5
I tried leaning out the -40PW to 3 and the 170PW to 1 and it still flooded out on one attempt to start. Also, i noticed that my computer NEVER goes into clear flood mode. I set the threshold to 60, 80, and 90% and even though it shows 100% throttle at the bottom of my megatune window it still says Clear flood off.
