How do I get into COS3?

Here is your tune converted to "04073003". Which is a 2004 COS3. It is set up as a 5.3, M/T, DBW---STARTER TUNE. I set the MAP scaler to 190 for a 2bar MAP sensor. If you use a different MAP Sensor you will need to scale table C6301 accordingly. I scaled up table A0009 by 35%----Just as a starting point. You will need to input your injector data into the tune when you get your new injectors. You will need to "Full Flash" this calibration into your PCM when you are ready. You will need a good Wide Band O2 Sensor to input into your tuning logs. You should be spending a LOT of time on the EFILive forum in the Gen3 and Forced Induction Sections as well as studying the tutorials.

i really appreciate the help ive been up all night trying to figure out how to change to the custom os

The 2004 factory calibration will work just fine. I have done several and NEVER been able to out run the MAF table. GM's GMPX built several trucks and they did not use a COS.

Are EFILive's COS speed density calibrations?

EFILive COS may be operated jut like an OEM OS - MAF only, SD only, or blended (OEM style). While you could run the OEM OS in MAF only mode (as long as you don't exceed the airflow limits), a well tuned SD configuration (or blended configuration) will yield a "sharper" tune, with better throttle response.

The HPT 2 bars are SD calibrations. SD calibration lack a lot. It would take me hours to explain everything that the MAF is a function of

Good to here the EFILive COS use MAF's. The 2004 MAF limit is 12,000 hz. The most I got out of a Maggie was 11,250 and the Whipple almost 11,700. The Whipple truck was spun past the RPM range

I just ran a C6 with a Lingenfelter E force supercharger yesterday. I pulled the data-log up and found that it maxed out at as low as 4800 in 1st and the rest of the gears about 6000, I ran it to 6800 with it maxed out. I never thought that would have happened on this car.

Trying to answer the OP's questions about a COS ... not interested in a Coke vs Pepsi debate regarding SD vs MAF tunes. You will find very knowledge people will that will line up on either side of that fence. I work with mainly E38 / E67 these days ... a lot of folks seem to want an A6 in their dream car.

MAF tunes are prevalent for several reasons - they are quick and easy (meaning they cost less), they require less knowledge / experience on the part of the person doing the tune, and only EFILive has these (E38 / E67) VE or VVE tables native within the tuning software.

Having driven and tuned a lot of these, the SD tunes (or SD and MAF combined) always seem a little crisper during rapid throttle transitions, than do the MAF only tunes - but perhaps this is merely my person bias.

i installed the new custom os and tune what do i need to do to get it started now

I understand what you are stating. I do all the VE tables and the MAF table when I tune.

If you read the original post you will see that a COS will not fix his issue. He is not out flowing the MAF at 4500 rpm's with a 5.3L
