Excellent job and can't believe how "factory" it really does look in that engine bay. Very sharp!

So I have the 8.1L in my 2004 suburban and have heard that it's been de-tuned from the factory. Are you suggesting that I do have some "unreleased" power in there somewhere?!? I do love the way the truck tows and in my experience, more snappy than the 6.0L....but there's more? Please share
