Sorry, I wasn't being clear, watch your youtube vid and you will see the A/F read just dashes a few times.
Yeah that was my vid. When I let off the gas it goes to dashes because there is no fuel being injected into the engine and just air moving out the exhaust. This is normal. When I simply turn the car off the A/F will still register because there are still fumes in the exhaust, when you lift off for a second or two while driving down the road in gear the engine pumps these fumes out and you get the dashes. Oh and its an AEM UEGO gauge.

boy i hope i have no problems when i go get tuned with the vortech...ive been checking my car over daily
Just make sure your belt is tight and you don't have any leaks. Do a boost pressure test as discussed earlier in this thread. I had to drive over 600 miles to get my car tuned so I know what you are going through. I later found a major boost leak because I didn't think of doing a pressure test prior. I prolly would of gotten 10-15 more whp and a more accurate tune had I found that leak prior.

ive read around a little on homemade pressure test kit, ill have to look some more, could u pm me with details on what i will need and exactly what i need to do and ill go do that now...yeah i have a 7 hour trip there and 7 hour trip back...gonna be tough but not gonna boost it one time till its tuned, i just wanna get the most out of it and not have leaks!! thanks man

So simple. Nice. As far as checking for leaks- you could always use an air pressure gauge to see if it is holding air or not. Then hunt it down.
Or a boost gauge. Hopefully if you have FI you will have one of these too. I wouldn't pressurize much more than 10-15 psi though. This pressure test kit can also help find exhaust leaks since the exhaust tips is where it is capped off.

thanks man, im gonna do it like u did, soon as i get my high flow cats on, they are supposed to be here today or tomorrow, so after i put em on im gonna pressure test the whole thing and find any leaks i might have..hopefully not though..
