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 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

Good lord man, do you speak just to hear the sound of your own voice ?

Of course I read his original post - that is why I chose to participate in this thread. Without a COS and a 2 bar MAP sensor, the only tuning option available is MAF only - eliminating SD and blended MAF & SD (OEM style) as options. Better to have three tuning options rather than just one.
