Very interesting!

What I've gathered from the video:
- 100% stock engine is good up to about 700-750hp (that includes stock turbos, stock fuel system)
- this is where we will max out with Stage 2 tunes with catless downpipes and E85
- and this will literally cost like $1500 ($600 for BM3, $600 for down pipes)

- Up to 1050hp is possible on stock engine internals with upgraded turbos, upgraded fuel system/port injection and cooling system
- my thoughts on this point is that this will cost around 10k-12k but that's incredibly cheap for that kind of level of power
- the question here is how the transmission will handle it
