If at all possible I need you to be more specific; just give me one number: 450, 500, or 800.

For example, 450rwhp is achievable via BPU++++, with a low mileage/hours engine (i..e GREAT compression and leakdown numbers) and a low mileage/hours set of turbos. However 500whp is NOT feasibly achievable via BPU++++, regardless of engine/turbos condition.

If you want 800 later, you will 100% for sure need to uninstall and resell some aftermarket BPU parts that you are buying now, at that time. If you're okay with doing this, let's just completely forget about 800 for now. However, if you're not okay with the inconvenience and cost of buying, installing, uninstalling and reselling BPU-specific parts, let's just get you to 800 right now. Just mho, fwiw.

Lastly, note that there's no need to "hope". We can absolutely 100% for sure achieve any one of these numbers. Any one of them is simply a matter of carefully invested $, time, and expertise.

True, but you'll get all you need for BPU with a $300 downpipe. Just so no one else reading this thread is misled, you really don't need to buy the two together.
