what did that shop say about it, did they think there was a problem or that it was normal with the heat?
if the dom is fully spooled by 4k rpm and so is vf then you would think they would overlap there and not at 5k. im gonna have someone test the engine
Shop said it was normal. They didn't think there was anything wrong with it. Although they said making my exhaust a full 3" back would help spool and power. Although I do wonder if the stock muffler would cause me to lose 50hp...
My other theory of lack of power is due to the Process West TMIC pipe bends to support the DOM for legacy fitment. Maybe this really kills the power? I do have to wonder if the stock turbo intake is collapsing, but I kind of doubt it.
