First, it's a good mechanic that knows his limitation and is honest about the tying up the rack reason. I have only one lift, and it means I cannot do anything else if a broken car is sitting on it for any reason. I can respect his reasons.

Second, you are in Bakersfield and it's not LA or Bay Area where there are 100,000 Porsches. You might want to learn how to do this or job it out to someone who is willing to take it on, out of town even.

As for the Porsche vs Audi thing, I have both but I do not know there is a distinction between flashing vs solid CEL. Both are bad to me. I do not remember ever seeing a flashing CEL on any of my Porches, or the ones I worked on. However, if there is ever a IMS related CEL on your Porsche, it is actually too late. You are way past time to open your wallet to a large check. Don't count on the CEL to catch your IMS problem. The thing to do is to take care of it preemptively.

As for the deviation pattern to look for, you want to see no more than 6 degrees of cam deviation from perfect alignment. You also want both cams to have fairly close to each other values. Widely different values mean some kind of problems even if it is not IMS related. Chain wear, chain pads wear, tensioner assembly issues. When you step on the gas to 3000 rpm, you want to see a jump in actual cam degrees to 20 to 30 advance (don't quote me on that number, but it is big).
