Check out their twin turbo Tahoe - I am going to post a link as it looks like something else!
May be visiting them for a couple of tunes, and maybe a turbo for my 5.3 Yukon.
Thanks

You can get away with running your current OS with the 2Bar, it is just a bit more complicated than using a custom OS, and leaves you with a bit less precision. As long as you have your MAF hooked up, you won't notice any issues with the decrease in precision.
A 2 bar tune is definitely a bit safer. If your MAF fails and you default into VE mode, then you still have accurate fueling in boost, whereas with a 1 bar sensor, once you hit boost the PCM has no idea what to provide for fueling.
Another benefit is you can go to an SD tune on a boosted vehicle, which has a whole plethora of benefits (and a few drawbacks).
BTW, I can help you get rolling with a 2 bar tune if you want. Do you have EFI Live Personal or Commercial?

You messed up by offering to help because now I'm gonna bother you when I get it ready.
So you spend $850 on it and got the commercial version. Perfect, you have the ability to do a full flash and change to the custom OS, which is quite nice from what I hear. Boost VE, dual SD spark maps, semi-closed loop (Ben @EFI101 is getting 16mpg out of a 2500 HD 6.0L with this) and more.
I'm not sure on the exact part number of the MAP. I swapped mine a long time ago and forgot. It has been posted around here before as well as forum.efilive.com, so it should be easy to find. Price was in the 50-100 range if I remember correctly.
