I have of course checked at first if all connections for hoses, sensors, etc. are available - and luckily you will miss nothing when the conversion is done, but as written above its not just completely P'n'P - will detail in the installation documentary later !
I cannot tell if it will get HP, even though the lower manifold is not just bolted together with some spare metal pieces but constructed and rendered with the same software manufacturers use and build to meet and exceed OEM quality and fitment.
First calculations show it will be very hard to gain HP on N/A's throughout the whole power band because of the VVEL but I'm positive we can do at least much better than the M370. Maybe you will need a proper retune to take full advantage but this will all be tested from start to end and documented very detailed as soon as the construction and building part has been a success.
I'm glad you like this project, motivates me to bring it to live as soon as possible
