Ok I think I might know the problem. Before I left for vegas I reinstalled a tune, so I'm sure I didn't do all the stuff in the drive cycle. Is that stuff from the list just "not ready"?

Sounds like to you need to reinstall a lot of stock items, or go to a smog station that will "look past" these problems.

A complete driving cycle should perform diagnostics on all systems. A complete driving cycle can be done in under fifteen minutes.
To perform an OBDII Driving cycle do the following:
- Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 50°C (122°F) and within 6°C (11°F) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.
- Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire and if closed loop is achieved, Fuel Trim.
- Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 88km/hr (55mph) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.
- Hold Steady Speed. Hold a steady speed of 88km/hr (55mph) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.
- Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 32km/hr (20 mph). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.
- Accelerate. Accelerate at 3/4 throttle until 88-96 km/hr (55-60mph). This will perform the same diagnostics as in step 3.
- Hold Steady Speed. Hold a steady speed of 88km/hr (55mph) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.
- Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.

Plain and simple.....your PCM says your smog crap is not working. Make sure all your smog stuff is hooked up and working and is being monitored by the PCM. Disabling the smog stuff on these LS motors does not gain anything.......only trouble.
I pass my smog (OBD II) test with flying colors every year in NV.

I'm just happy the highway roll racing ****** crew made it over here. Hopefully we can meat up and let them show us their vtaks. The coolest part about roll racing is when you get shut the **** up poser ricer roll race queers. Any sub 2800lb car that makes 500whp is ******* stupid because its undrivable on a real track, which you'll never see because you don't have a real job. I highly recommend that you make a plan for your life, or you're going to be a virgin for all eternity. You should start by moving out of your grandmother's basement. Next I recommend an extreme amount of cardio, and its probably not a bad idea to buy a razor and cut off the internet connection. You should also probably stop masturbating so much with that death grip if you're ever going to get you're baby dick half hard at the first sight of a woman you may possibly have a chance of communicating with. However, most importantly, don't get your hopes up because I'm pretty much everything every woman on earth wants, you're the compromise. I'm strong, sexy, intelligent, hung, affluent, cultured, and I'll be the one you hate, the one you want to be so bad, the one you'll thank in 5-years when you get there and look back on this post and thank me for showing you the things that you daddy never did. I believe in you son, its time to be a man.
