I'm sure you are already aware, but installing an aftermarket intake without a tune, or MAF rescaling, is not recommended. After readling a lot, I actually just went back to a stock system, with the exception of the turbo inlet hose and my intake temperatures have decreased. I have not noticed any difference in power. My AFRs are more stable to boot. For the record, I did rescale my MAF because I was tuned with a short ram.
